**Note: 1.** Do not use an Inverter output for the Power Supply. Inverters with an output frequency of 50/60 Hz are available, but the rise in the internal temperature of the Power Supply may result in ignition or burning. 

**2.** Refer to _Engineering Data (15-W, 30-W, 50-W, 100-W, 150-W Models)_ on page 9 to 11 for details. 

**3.** If the output voltage adjuster (V. ADJ) is turned, the voltage will increase by more than +20% of the voltage adjustment range. If the adjuster is turned too far, it may activate the overvoltage protection function and interrupt the output. 

   - When adjusting the output voltage, confirm the actual output voltage from the Power Supply and be sure that the load is not damaged. 

**4.** To reset the protection, turn OFF the input power for three minutes or longer and then turn it back ON. 

**5.** Conducted emissions: The noise value is affected by factors such as the wiring method. The Power Supply conforms to Class B when the aluminum plate is laid under the Power Supply. For 15-W models, insert a clamp filter (ZCAT2436-1330 by TDK: 50 Ω min. [50 to 500 MHz], or the equivalent) in the output wire to reduce noise. 

**6.** Radiated emissions: The noise value is affected by factors such as the wiring method. The Power Supply conforms to Class B when the aluminum plate is laid under the Power Supply. For 150-W models, insert a clamp filter (ZCAT2017-0930 by TDK: 35 Ω min. [50 to 500 MHz], or the equivalent) in the input wire to reduce noise. 

**7.** The weight indicated is for bottom mounting, open-frame models. 

**8.** A@: Sinking type (NPN) 

   - P@: Sourcing type (PNP) 

**9.** With the S8VM-15024@@, the output current for UL1604 certification is 6.3 A.

- **Note: 1.** Do not use an Inverter output for the Power Supply. Inverters with an output frequency of 50/60 Hz are available, but the rise in the internal temperature of the Power Supply may result in ignition or burning. 

   **2.** Refer to _Engineering Data (300-W, 600-W, 1,500-W Models)_ on page 15 to 17 for details. 

   **3.** If the output voltage adjuster (V. ADJ) is turned, the voltage will increase by more than +20% of the voltage adjustment range. If the adjuster is turned too far, it may activate the overvoltage protection function and interrupt the output. When adjusting the output voltage, confirm the actual output voltage from the Power Supply and be sure that the load is not damaged. 

   **4.** To reset the protection, turn OFF the input power for three minutes or longer and then turn it back ON. Alternatively, turn OFF the remote control signal and then turn it back ON again. 

   **5.** Conducted emissions: The noise value is affected by factors such as the wiring method. The Power Supply conforms to Class B when the aluminum plate is laid under the Power Supply. For 600-W models, insert a clamp filter (ZCAT3035-1330 by TDK: 100 Ω min. [50 to 500 MHz], or the equivalent) in the input wire, and ring core (HF60T38X14X22 by TDK: 16 Ω typ. [1 MHz], 46 Ω typ. [10 MHz], or the equivalent) in the output wire to reduce noise 

   **6.** Radiated emissions: The noise value is affected by factors such as the wiring method. The Power Supply conforms to Class A when the aluminum plate is laid under the Power Supply (1,500-W models). 

   **7.** The measuring method conforms to JEITA standard RC-9131A. Refer to _Ripple_ under _Safety Precautions_ on page 32. 

   **8.** The Power Supply will not conform to safety standards if the customer replaces the fan.

## **300W/600W/1,500W** 

**Note:** Refer to page 15. 

- **Note: 1.** Internal parts may occasionally be deteriorated or damaged. Do not use the Power Supply in areas outside the derating curves (i.e., the area shown by shading A in the above graphs). 

   **2.** If there is a derating problem, use forced air-cooling. 

   **3.** When mounting two or more Power Supplies side-by-side, allow at least 20 mm spacing between them. Multiple 100- and 150-W models cannot be used side by side. Be sure to install the Power Supplies as far away from heat-generating sources as possible. As a reference value, allow at least 50 mm spacing on the right and left sides. If only 20 mm spacing is allowed, use the Power Supply at a load ratio of 80% or less. 

   **4.** When using 150-W models for a long period of time at an input voltage of 90 VAC or lower, reduce the load to 80% or less of the above derating curves.

## ■ **Remote Sensing Function** 

## **(S8VM-100** @@@@ **/150** @@@@ only **)** 

This function compensates a voltage drop on the load lines. To use this function, connect after removing the two short bars of the remote sensing terminal.

- **Note: 1.** Use a 2-conductor shielded cable as a connection wire (*1). **2.** Use as thick a wire as possible since high voltage drops on the load lines (*2) may activate the overvoltage protection function. 

   **3.** Use when the voltage drop is 0.3 V or lower. 

   **4.** When the +S and −S terminals are opened with the short - 

   bar removed, the overvoltage protection function is activat ed and the output voltage will be cut off. 

   **5.** If the load line is too long, use an electrolytic capacitor in the following 3 locations: 

      - 1) Across the load terminals 

      - 2) Between the +S terminal and + terminal 

      - 3) Between the −S terminal and − terminal 

      - Select the capacity of the connected capacitor from between several tens to several hundreds of µF as a guide, and then determine the capacity when actually connecting the capacitor between terminals as shown below.

**2.** Use the metal plate as the mounting panel (*1). 

**3.** Install the Power Supply so that the air flow circulates around the Power Supply, as the Power Supply is designed to radiate heat by means of natural air flow.

## ■ **Overload Protection** 

The Power Supply is provided with an overload protection function that protects the Power Supply from possible damage by short-circuit and overcurrent. 

When the output current rises above 105% min. of the rated current, the protection function is triggered, automatically decreasing the output voltage. When the output current falls within the rated range, the overload protection function is automatically cleared.

The values shown in the above diagrams are for reference only. 

- **Note: 1.** Internal parts may occasionally deteriorate or be damaged if a short-circuited or other overcurrent state continues during operation. 

## ■ **Overvoltage Protection** 

Consider the possibility of an overvoltage and design the system so that the load will not be subjected to an excessive voltage even if the feedback circuit in the Power Supply fails. When an excessive voltage that is approximately 140% of the rated voltage or more is output, the output voltage is shut OFF, preventing damage to the load due to overvoltage. Reset the input power by turning it OFF for at least three minutes and then turning it back ON again.

      - **Note: 1.** Do not turn ON the input power again until the cause of the overvoltage has been removed. 

         **2.** The overvoltage protection function may be activated when the output voltage adjuster (V.ADJ) is set to a value that exceeds +20% of the rated output voltage. 

         **3.** When the +S and −S terminals are opened with the shortbar removed, the overvoltage protection function is activated and the output voltage will be cut off. 

   - Do not continue an overload state for longer than 30 seconds. Eliminate the overcurrent state as soon as possible. 

**2.** Internal parts may possibly be deteriorated or damaged if the Power Supply is used for applications with frequent inrush current or overloading at the load end. Do not use the Power Supply for such applications. 

## ■ **Undervoltage Alarm Function (Indication and Output)** 

## **(Only S8VM-** @@@ **24A** @ **/P** @ **)** 

If an output voltage drop is detected with an S8VM-@@@24A@/P@ with undervoltage alarm function, the DC LOW indicator will light to notify of an output error. The transistor also sends an output externally to notify of the error (except for the S8VM-01524A@ and S8VM-03024A@). Transistor Output: Sinking type: (NPN) (S8VM-@@@24A@) Sourcing type: (PNP) (S8VM-@@@24P@) 30 VDC max., 50 mA max., Residual voltage when ON: 2 V or less, Leakage current when OFF: 0.1 mA or less

- Undervoltage Alarm Function 1 (DC LOW1) 

Only a momentary voltage drop is detected. Detection voltage is automatically adjusted internally by detecting the output voltage (approx. 2.7 V lower than the voltage output at an output voltage of 24.0 V). 

During detection, the transistor is OFF (with no continuity across 8 and 10) and the LED (6: Yellow) lights. (The Undervoltage Alarm Function 1 is used as a latch holding function.) 

- Undervoltage Alarm Function 2 (DC LOW2) 

Detection voltage is set to approx. 20.0 V (from 18.0 to 21.6 V). 

During detection, the transistor is OFF (with no continuity across 9 and 10) and the LED (7: Red) lights. 

- **Note: 1.** This function monitors the voltage at the Power Supply output terminals. To check actual voltage, measure voltage on the load side. 

   **2.** Gradual voltage drop is not detected by the Undervoltage Alarm Function 1 (DC LOW1). 

   **3.** Once a voltage drop in the output voltage is detected by Undervoltage Alarm Function 1 (DC LOW1), the transistor turns OFF and status of the LED (6: Yellow) light is maintained. To reset the function, turn OFF the input power for 60 seconds or longer, and then turn it ON again. 

   **4.** If the output voltage remains at 15 V or lower for several seconds when using Undervoltage Alarm Function 1 (DC LOW 1), the output hold status for detection may be reset.

- **Note: 1.** Internal parts may occasionally be deteriorated or damaged. Do not use the Power Supply in areas outside the derating curves (i.e., the area shown by shading A in the above graph). 

   **2.** When mounting two or more Power Supplies side-by-side, allow at least 20 mm spacing between them. Always provide at least 50 mm of mounting space for the surface with the fan mounted. Be sure to provide at least 50 mm (S8VM300@@C/600@@C) or 100 mm (S8VM-15224C) of mounting space on the opposite side of the surface with the fan mounted. 

   **3.** When using the 1,500-W model for a long period of time at an input voltage of 90 VAC or lower, reduce the load to 80% or less of the above derating curve. 

   **4.** The ambient temperature is specified at a location 50 mm in front of the center of the Power Supply's front panel.

- **Note: 1.** The internal parts may occasionally deteriorate or be broken due to adverse heat dissipation depending on the mounting status. Do not use the Power Supply in any mounting direction other than those specified. 

   **2.** Use the metal plate as the mounting panel (*1). 

   **3.** To ensure sufficient cooling, do not cover the air holes located on the side the fan is mounted and the opposite side. 

   **4.** Mounting screw tightening torque (recommended value: M4 (1.27 N·m)) 

      - The screws must not protrude more than 6 mm inside the Power Supply. 

## ■ **Remote Sensing Function** 

This function is used to compensate for voltage drops on the load lines. Connect the +S pin (pin 2 on CN) to the positive load terminal and the −S pin (pin 4 on CN) to the negative load terminal to enable remote sensing. When not using the remote sensing function, use the standard supplied connector. The +S and +V pins (pin 1 on CN) and the −S and −V pins (pin 3 on CN) will be connected.

- **Note: 1.** Use 2-conductor shielded cable as connection wire (* 1). 

   **2.** Use as thick a wire as possible since high voltage drops on the load lines (* 2) may activate the overvoltage protection function. 

   **3.** Use when the voltage drop is 0.3 V or lower. 

   **4.** If the sensing line is too long, it is necessary to put an electrolytic capacitor across the load terminals. The electrolytic capacitor may generate heat due to the ripple current, depending on connected load. Therefore, the electrolytic capacitor must have a ripple current allowance higher than the output ripple current. 

   **5.** The stability and accuracy of the output will deteriorate if the short bar is missing or if the +S and −S pins are open. Always connect the +S and −S pins. 

   **6.** Remove the standard supplied connector and prepare a connector harness separately. 

**15** 

**S8VM** 

## ■ **Remote Control Function** 

This function turns outputs ON and OFF using an external signal while input voltage is applied, using the +RC pin (pin 7 on CN) and the -RC pin (pin 8 on CN). Connect a switch or transistor to the +RC and -RC pins to use the remote control function. When not using this function, the +RC and -RC pins are shorted by using the standard supplied connector.

- **Note: 1.** Use 2-conductor shielded cable or twisted-pair cable as connection wire. 

   **2.** The remote control circuit is isolated from the input and output circuits of the power supply. 

   **3.** Remove the standard supplied connector and prepare a connector harness separately. 

## ■ **Power Failure Alarm Function** 

The power failure alarm indicator will light red to indicate an output voltage error if overload, overvoltage, or overheat protection is activated, if a drop in the input voltage causes the output voltage to drop, if the built-in fan motor stops, and during remote control standby. The alarm is also output externally by a transistor. 

Transistor output: 30 VDC max., 50 mA max. Residual voltage when ON: 2 V max. 

Leakage current when OFF: 0.1 mA max. 

Alarm detection voltage: Approx. 80% of output voltage setting During detection, the transistor is OFF (with no continuity across pins 11 and 12 on CN), and the LED (red) lights.

## ■ **Overload Protection** 

The Power Supply is provided with an overload protection function that protects the Power Supply from possible damage by overcurrent. When the output rises above 105% of the rated current, the protection function is triggered, automatically decreasing the output voltage. 

## **S8VM-300** @@ **C/600** @@ **C** 

When the output current returns within the rated range, overload protection is automatically cleared. 

## **S8VM-15224C** 

Outputs are interrupted if an overload continues for 5 seconds or more. To reset the Power Supply, leave the input power OFF for more than 3 minutes and then turn it ON again. Alternatively, turn OFF and ON the remote control signal.

- **Note: 1.** If the Power Supply has been short-circuited or supplied with an overcurrent for longer than 30 seconds, the internal parts of the Power Supply may occasionally be deteriorated or damaged. 

   **2.** The internal parts may possibly be deteriorated or damaged. Do not use the Power Supply for applications where the load causes frequent inrush current and overload.

## ■ **Overvoltage Protection** 

Consider the possibility of an overvoltage and design the system so that the load will not be subjected to an excessive voltage even if the feedback circuit in the Power Supply fails. When an excessive voltage that is approximately 140% of the rated voltage or more is output, the output voltage is shut OFF, preventing damage to the load due to overvoltage. Reset the input power by turning it OFF for at least three minutes and then turning it back ON again. Alternatively, turn OFF and ON the remote control signal.

The values shown in the above diagram are for reference only. 

- **Note: 1.** Do not turn ON the input power again until the cause of the overvoltage has been removed. 

   **2.** The overvoltage protection function may be activated when - 

   the output voltage adjuster (V.ADJ) is set to a value that ex ceeds +20% of the rated output voltage. 

## ■ **Overheat Protection** 

The overheat protection circuit will operate and outputs will be shut OFF to protect the Power Supply if the ambient temperature rises, the fan stops, or other errors cause the Power Supply's internal temperature to rise. To reset the Power Supply, leave the input power OFF long enough for the Power Supply to cool sufficiently and then turn it ON again. Alternatively turn OFF the remote control signal long enough to cool sufficiently and then turn it ON again. 

## ■ **Peak Output Current** 

## **- (S8VM 30024C/60024C/15224C Only)** 

The peak current must satisfy the following conditions. Reduce the peak current according to the load rate of the derating curve. 

Input voltage range: 180 to 240 VAC Peak current pulse width: 10 s max. Duty: 35% max. 

Peak current value: Within the rated peak current Effective output current: Within the rated current

## ! **CAUTION** 

**==> picture [38 x 186] intentionally omitted <==**

Minor electric shock, fire, or Product failure may occasionally occur. Do not disassemble, modify, or repair the Product or touch the interior of the Product. 

Minor burns may occasionally occur. Do not touch the Product while power is being supplied or immediately after power is turned OFF. 

Fire may occasionally occur. Tighten terminal screws to the specified torque. 

15-, 30-, 50-, 100-, and 150-W models (1.6 N·m) 300-, 600-, and 1,500-W models (M4; 1.6 N·m, M5; 2.50 N·m, M8 bolts and nuts; 10.8 N·m) 

Minor injury due to electric shock may occasionally occur. Do not touch the terminals while power is being supplied. 

Minor electric shock, fire, or Product failure may occasionally occur. Do not allow any pieces of metal or conductors or any clippings or cuttings resulting from installation work to enter the Product. 

## ■ **Precautions for Safe Use** 

## **Mounting** 

Ensure sufficient heat dissipation when installing the Power Supply to increase its long-term reliability. 

Use the metal plate as the mounting panel. 

When cutting out holes for mounting, make sure that cuttings do not enter the interior of the Power Supply. 

The amount of installation spacing required between Power Supplies depends on the capacity. Refer to the following table. 

## **15/30/50/100/150-W Models** 

Natural cooling is used, so mount the Power Supply so that there is airflow around it. 

Improper mounting will interfere with heat dissipation and may occasionally result in deterioration or damage of internal parts. Use the Power Supply within the derating curve for the mounting direction that is used. 

The internal parts may possibly be damaged if mounting screws are over inserted. Refer to _Dimensions_ on page 19 to 21 for maximum depth of insertion inside the Power Supply.

**Note: 1.** Convection of air 

**Note:** If more than one S8VM-100@@@@/150@@@@ Power Supply is mounted together, install them as far away from sources of heat as possible. If only 20 mm of space is available on the right and left sides of a Power Supply (see note 2.), use the Power Supply at a load ratio of 80% or less. 

## **300/600/1,500-W Models** 

A forced-air cooling method with a fan is used. To ensure sufficient cooling, do not cover the air holes located on the side the fan is mounted and the opposite side. 

Improper mounting will interfere with heat dissipation and may occasionally result in deterioration or damage of internal parts. Do not use the Power Supply in any mounting direction other than those specified. 

The internal parts may possibly be damaged if mounting screws are over inserted. The screws must not protrude more than 6 mm inside the Power Supply.

**5.** Use a metal plate as the mounting panel. 

## **Wiring** 

Connect the ground completely. A protective earthing connection stipulated in safety standards is used. Electric shock or malfunction may occur if the ground is not connected completely. 

Minor fire may possibly occur. Ensure that input and output terminals are wired correctly. 

Do not apply more than 100-N force to the terminal block when tightening it. 

Be sure to remove the sheet covering the Power Supply for machining before power-ON so that it does not interfere with heat dissipation. 

**32** 

**S8VM** 

Use the following material for the wires to be connected to the S8VM to prevent smoking or ignition caused by abnormal loads. Over heating or fire can result from inadequately sized wiring materials when problems occur at the load. As a general rule, always select wire sizes suitable for at least 1.6 times the rated current. Refer to the wiring manufacturer's recommended allowable current and voltage drop specifications for information when selecting wiring materials. 

## **Recommended Wire Sizes** 

|**Terminal**|**Model**|**Model**|**Recommended wire size**|
|---|---|---|---|
|Input|S8VM-015@@@@<br>S8VM-030@@@@<br>S8VM-050@@@@<br>S8VM-100@@@@<br>S8VM-150@@@@|(M3.5)|AWG24 to AWG14<br>(0.205 to 2.081 mm2)|

The current rating for the output terminals on the S8VM-300@@C is 40 A per terminal. The current rating for the output terminals on the S8VM-600@@C is 60 A per terminal. Use two terminals together if a current exceeding the terminal rating is used. 

Use min. 60°C or 60/75°C wire. 

Use copper conductors only. 

## **Undervoltage Alarm Output Connector Harness Manufacture Method** 

The following products are provided with the S8VM-05024A@/P@, S8VM-10024A@/P@ and S8VM-15024A@/P@ for the undervoltage alarm transistor output wiring.

|---|---|---|---|
|||S8VM-15024A@/P@||

|**Housing (provided)**|XHP-3|||
|**Terminal (provided)**|BXH-001T-P0.6 or SXH-001T-P0.6|||



Be sure to prepare the connector according to the following instructions to ensure correct wiring. For details, refer to the JST catalog. 

- Use a wire size of AWG28 to AWG22. 

- The guideline for the length of sheath to be stripped from the wire is 2.1 to 2.6 mm. 

- Use either a YC or YRS Crimping Tool (manufactured by JST) to crimp the terminal and wire. 

- Be sure to insert the crimped terminal wires into the housing fully until a click is heard. Also, make sure that the wires attached to the housing are securely locked in place. 

## **Signal I/O Connector Harness Manufacture Method** 

The S8VM-300@@C/600@@C/15224C are using PHD connector (manufactured by JST). 

|Connector|S8VM-300@@C/600@@C/15224C|Manu-<br>factured<br>by JST|
|---|---|---|
||S12B-PHDSS||
|Housing|PHDR-12VS||
|Terminal|SPHD-001T-P0.5 or BPHD-001T-P0.5||



Be sure to prepare the connector according to the following instructions to ensure correct wiring. For details, refer to the JST catalog. 

- Use a wire size of AWG26 to AWG22. 

- The guideline for the length of sheath to be stripped from the wire is 2.3 mm. 

- Use a YC Crimping Tool (manufactured by JST) to crimp the terminal and wire. 

- Applicable wire per barrel size is UL1007 (standard wire) and its equivalent standard wire can be used. Use UL1061 or its equivalent standard wire for AWG22 wires, because the wire insulation outer diameter of UL1061 is small. 

- Be sure to insert the crimped terminal wires into the housing fully until a click is heard. Also, make sure that the wires attached to the housing are securely locked in place. 

## **Installation Environment** 

Do not use the Power Supply in locations subject to shocks or vibrations. In particular, install the Power Supply as far away as possible from contactors or other devices that are a vibration source. Install the Power Supply well away from any sources of strong, highfrequency noise and surge. 

## **Operating Life** 

The life of a Power Supply is determined by the life of the electrolytic capacitors used inside. Here, Arrhenius Law applies, i.e., the life will be halved for each rise of 10°C or the life will be doubled for each drop of 10°C. The life of the Power Supply can thus be increased by reducing its internal temperature. 

## **Ambient Operating and Storage Environments** 

Store the Power Supply at a temperature of −25 to 65°C and a humidity of 25% to 90%. 

The Internal parts may occasionally be deteriorated or damaged. Do not use the Power Supply outside the derating range (i.e., under conditions indicated by the shaded area ( ) in the derating curve diagrams on pages 9 and 15.) 

Use the Power Supply at a humidity of 30% to 85%. 

Do not use the Power Supply in locations subject to direct sunlight. Do not use the Power Supply in locations where liquids, foreign matter, or corrosive gases may enter the interior of the Power Supply. 

## **Overload Protection** 

If the Power Supply has been short-circuited or supplied with an overcurrent for longer than 30 seconds, the internal parts of the Power Supply may occasionally be deteriorated or damaged. 

Internal parts may possibly be deteriorated or damaged if the Power Supply is used for applications with frequent inrush current or overloading at the load end. Do not use the Power Supply for such applications. 

## **Dielectric Strength Test** 

If a high voltage is applied between an input and the case (PE/FG), it will pass though the LC of the built-in noise filter and energy will be stored. If the high voltages used for dielectric strength testing are turned ON and OFF with a switch, timer, or similar device, impulse voltage will be generated when the voltage is turned OFF and internal parts may possibly be damaged. To prevent the generation of impulse voltages, reduce the applied voltage slowly with a variable resistor on the test device or turn the voltage ON and OFF at the zero-cross point. 

When performing the test, be sure to short-circuit all the output terminals to protect them from damage. 

Check the waveform of the applied voltage while testing. High voltage due to distortions of the applied voltage may be produced depending on the type of testing equipment. 

**33** 

**S8VM** 

## **Insulation Test** 

When performing the test, be sure to short-circuit all the output terminals to protect them from damage. 

## **Inrush Current** 

When two or more Power Supplies are connected to the same input, inrush current is added to the total current. Select fuses and circuit breakers giving sufficient consideration to the fusing or operating characteristics so that fuses will not burn and breakers will not break due to inrush current. 

## **Output Voltage Adjuster (V.ADJ)** 

Default Setting: Set at the rated voltage 

Adjustable Range: Adjustable with output voltage adjuster (V.ADJ) on the front panel of the Power Supply from −20% to 20% of the rated − output voltage ( 10% to 20% of the rated voltage for S8VM@@@24A@/P@). Turning clockwise increases the output voltage and turning counterclockwise decreases the output voltage. 

The output voltage adjuster (V.ADJ) may possibly be damaged if it is turned with unnecessary force. Do not turn the adjuster with excessive force. 

After completing output voltage adjustment, be sure that the output capacity or output current does not exceed the rated output capacity or rated output current. 

The output voltage may increase beyond the allowable voltage range (up to +20% of the rated voltage) depending on the operation of the output voltage adjuster (V.ADJ). When adjusting the output voltage, check the output voltage of the Power Supply and be sure that the load is not damaged. 

When increasing the output voltage to more than +20% of the rated value using the output voltage adjuster (V. ADJ), the overvoltage protection function may operate. 

## **(S8VM-** @@@ **24A** @ **/P** @ **Only)** 

Turn the output voltage adjuster (V.ADJ) slowly. When decreasing the output voltage quickly, or when adjusting the output voltage to less than −10% of the rated value, the undervoltage alarm function may operate. 

## **Ripple** 

## **(S8VM-15224C Only)** 

The rated ripple noise voltage was measured using a measuring circuit that conforms to the JEITA standard RC-9131A.

- **Note: 1.** If the load is short-circuited, a reverse voltage may be applied inside the Power Supply unit, and this may possibly cause the deterioration or damage of the Power Supply unit. Connect the diode as shown in the figures. Use the following guidelines to select the diode to be connected. 

|**Type**|**Schottky Barrier diode**|
|---|---|
|Dielectric strength<br>(VRRM)|Twice the rated output voltage or<br>above|
|Forward current (IF)|Twice the rated output current or<br>above|



**2.** Though Power Supplies having different specifications can be connected in series, the current flowing through the load must not exceed the smaller rated output current. 

## **Parallel Operation**

Use 2-conductor shielded cable as connection wire (* 1). 

Adjust the output voltage of each Power Supply to the same value within 1% of the rated voltage or so that the difference in the output voltage is 100 mV or less, whichever is smaller, using the output voltage adjuster (V. ADJ). 

Parallel operation is used to increase static capacity. The output voltage may drop with sudden load fluctuations. 

There may be steps in the rising waveform of the output voltage during parallel operation. 

Remove the standard supplied connector and prepare a connector harness separately. 

## **In Case There Is No Output Voltage** 

## **15/30/50/100/150-W Models** 

The possible cause for no output voltage may be that the overload protection or overvoltage protection has operated. The internal protection circuit may operate if a large amount of surge voltage such as a lightening surge is applied to the input. 

If there is no output voltage even after checking the following points please contact your OMRON representative. 

## **Check the overheat protected status.** 

Turn OFF the input power and leave it OFF until the Power Supply cools sufficiently. Turn it ON again to see if this clears the condition. 

## **Check if the built-in fan motor has stopped.** 

Check if the built-in fan motor has stopped. The fan is a consumable part. 

## **Check the remote control function.** 

Check if the +RC and -RC pins are open. Make the correct connections as specified. 

## **Fan Replacement** 

## **300/600/1,500-W Models** 

Consult with OMRON regarding fan replacement. OMRON will replace fans for a fee. A replacement Fan Unit (S82Y-VM@@FAN) is available. Use the curve in the graph below as a rough measure of replacement timing.

- The Power Supply will not conform to safety standards if the cus tomer replaces the fan. 

## **Check the overload protected status.** 

Check whether the load is in overload status or is short-circuited. Remove the load wires when checking. 

## **Attempt to clear the overvoltage or internal protection function.** 

Turn OFF the input power once and leave it OFF for at least 3 minutes. Then turn it ON again to see if this clears the condition. 

Check whether the +S terminal and −S terminal are open, i.e., if the short bar has been removed. (S8VM-100@@@@/S8VM-150@@@@ only) 

Check if the output voltage has been adjusted to more than +20% of the rated voltage using the output voltage adjuster (V. ADJ). 

## **300/600/1,500-W Models** 

The possible cause for no output voltage may be that the overcurrent protection, overvoltage protection, or overheat protection has operated. Alternatively, the built-in fan may have stopped or the remote control function may be OFF. 

If there is no output voltage even after checking the following five points, please contact your OMRON representative. 

## **Check the overload protected status.** 

Check whether the load is in overload status or is short-circuited. Remove the load wires when checking. 

## **Attempt to clear the overvoltage protection function.** 

Turn OFF the input power once and leave it OFF for at least 3 minutes. Then turn it ON again to see if this clears the condition. Check whether the +S terminal and −S terminal are open. 

## **Buzzing Noise when the Input Is Turned ON** 

## **50/100/150/300/600/1,500-W Models** 

A harmonic current suppression circuit is built into the input power. This circuit can create noise when the input is turned ON, but it will last only until internal operation stabilizes and does not indicate any problem in the Power Supply. 

## **DIN Rail Mounting** 

## **15/30/50/100/150/300/600-W Models** 

When mounting to a DIN Rail, lower the S8VM onto the Rail until the Rail stopper (A) clicks into place, hook section A over the edge of the Rail and push in the direction of B. (B) To remove the S8VM from the DIN Rail, insert a screwdriver into section C and pull the S8VM away from the Rail. 30 mm min. (C) Rail stopper 

Check if the output voltage has been adjusted to more than +20% of the rated voltage using the output voltage adjuster (V. ADJ).
