- **Note:** Improper mounting will interfere with heat dissipation and may occasionally result in deterioration or damage of internal parts. It may also result in failure of the maintenance forecast monitor function. Use the standard mounting method only. 

## **Overload Protection** 

The load and the power supply are automatically protected from overcurrent damage by this function. 

Overload protection is activated if the output current rises above 105% of the rated current. 

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

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

   **2.** Internal parts may possibly deteriorate or be 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. 

## **Peak Output Current (S8VS-48024 only)** 

The peak current must satisfy the following conditions. Input voltage range: 200 to 240 VAC 

Peak current value: 30 A max. 

Peak current pulse width: 2 s max. 

Cycle: 60 s min. 

- **Note: 1.** Two seconds after the peak current is reached, the peak current limiting function operates to stop the peak current flow. 

   **2.** It takes 60 seconds for the peak current to be able to flow again. 

   **3.** The peak current limiting function prevents the peak current from flowing at 100 to 120 VAC.

## **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. If an excessive voltage that is approximately 130% of the rated voltage (but approximately 110% of the rated voltage for the S8VS-09024 DIDO S) or more is output, the output voltage is shut OFF. Reset the input power by turning it OFF for at least three minutes and then turning it back ON again.

## **Undervoltage Alarm Function (Indication and Output) (S8VS-** OL **24A** La **/S8VS-** CLL **24B / S8VS-** OIL **24BE** L] **Only)** 

> When output voltage drop is detected, an alarm ( Ag ¢ ) and lowest output voltage value are indicated alternately. The preset value of detection voltage can be changed in the setting mode. (From 18.5 to 27.5 V in 0.1-V steps. The value is fixed at 20.0 V for the S8VS-06024A / S8VS-06024B.) 

Further, an output (undervoltage output terminal (DC LOW)) to an external device is given from the transistor to notify of the error (excluding S8VS-06024A/S8VS-06024B/S8VSDIDO 24BE | ). (Output voltage drop = OFF, i.e., no continuity at the undervoltage output terminal (DC LOW).) 

Example: Outputting an Alarm When the Voltage Output by the S8VS-09024A OO Drops to the Set Value (19.0 V) or Lower 

: In the case that the output voltage drops below the set value (19.0 V) and an alarm is issued 

- **Note: 1.** Operation begins after about three seconds since the AC power is supplied. 

   **2.** The alarm is not indicated in the setting mode. 

   **3.** Press the (Mode Key (8)) after the output voltage is restored, to reset alarm indication. 

   **4.** The undervoltage alarm function may also operate when an interruption in AC input is not restored within 20 ms. 

   **5.** The undervoltage alarm function monitors the output terminal voltage of the Power Supply. To check the voltage accurately, measure the voltage at the load end.

## **Undervoltage Alarm Indication** 

LED (DC LOW: red) lights to warn of output voltage drop. Detection voltage is set to approx. 80% (75 to 90%) of the rated output voltage. 

**Note:** This function monitors the voltage at the power supply output terminals. To check actual voltage, measure voltage on the load side.

## **Indication and Output** 

When the Product is purchased, “ful” will be indicated. As electrolytic capacitors deteriorate, indication changes to “hlf” (Refer to page 30). “ful” will be indicated for the maintenance forecast display for approximately one month after the Power Supply is first turned ON. The accumulated value will then be displayed depending on the ambient conditions thereafter. (However, the “hlf” indication may not appear, depending on the usage environment and the set value for maintenance forecast.) 

## **S8VS-06024A:** 

After the remaining time to maintenance is reduced to less than two years, indication automatically changes to a value, which decreases from “1.5” to “1.0” to “0.5” to “0.0” (year) as the running hours increase. If the remaining time becomes less than 0.5 year, an alarm (a02) and “0.0” are indicated alternately.

If the maintenance forecast setting L (which can be set arbitrarily from 0.0 to 5.0 years in 0.5-year steps) is set to a value larger than two years, the indication automatically changes to a value (L - 0.5) after the remaining time to maintenance is reduced to the set years, and an alarm (a02) and the remaining time are indicated alternately. If the setting is less than 2.0 years, the indication changes to a value (1.5) after the remaining time becomes less than two years, and after the remaining time becomes less than the set time, an alarm (a02) and the remaining time (L - 0.5) are indicated alternately. If the alarm (a02) and a numeric value are indicated alternately, a transistor (maintenance forecast output terminal (Yrs)) will turn OFF to indicate the need for maintenance. (The transistor turns OFF when the maintenance forecast time is reached, i.e., there will be no continuity at the maintenance forecast output terminal.) 

In the case that the remaining time is reduced to smaller than 0.5 year and an alarm is issued. 

- **Note: 1.** The remaining time to maintenance is based on continuous operation, not including the time when the power supply is turned OFF. 

   **2.** “ful” will be indicated until approximately one month of time is accumulated to estimate the speed of deterioration and the output will remain ON (continuity at the maintenance forecast output terminal (Yrs)). 

   **3.** For details on the display, refer to _Relationship between Indicated Values and Output of Set Values_ under _Maintenance Forecast Monitor Function_ on page 30 _._

S8VS Switch Mode Power Supply 

**Display and Alarm Output Functions and Operating Procedures** 

## **Maintenance Forecast Monitor Function** 

The Power Supply is equipped with electrolytic capacitors. The electrolyte inside the electrolytic capacitor penetrates the sealing rubber and evaporates as time passes since it is manufactured, which causes deterioration of characteristics such as decreasing the capacitance, etc. 

Due to this deterioration of the characteristics of the electrolytic capacitor, the Power Supply decreases its performance as time passes. 

The maintenance forecast monitor function shows an approximate period left for maintenance of the Power Supply due to deterioration of electrolytic capacitors. When the period left for maintenance that the power supply forecasts reaches the set value, an alarm is indicated and an output signal is triggered. 

Use this function to know the approximate replacement timing of the Power Supply. 

**Note:** The maintenance forecast monitor function indicates an approximate period left for maintenance, based on deterioration of the electrolytic capacitor. It does not predict failures caused by other reasons.

**Note:** This function can be set only on the S8VS-09024A@@, S8VS-12024A@, S8VS-18024A@, S8VS-24024A@, and S8VS-48024A. 

## **Principle of Operation** 

The deterioration speed of the electrolytic capacitor varies considerably according to the ambient temperature. (Generally the speed follows “Rule of Two for every 10°C”; for every 10°C increase in temperature the rate of degradation doubles according to Arrhenius’s equation.) The S8VS-@@@24A@@ monitors the temperature inside the power supply, and calculates the amount of deterioration according to the running hours and inside temperature. Judging by this amount of deterioration, the power supply will give the alarm indication and output when the period left for maintenance reaches the set value. 

- **Note: 1.** Due to degradation of internal electronic parts, replace the power supply approximately 15 years after purchase even if indication and output of maintenance forecast monitor are not issued. 

   **2.** The maintenance forecast is accelerated or decelerated according to operating conditions. Periodically check indication. 

   **3.** Acceleration or deceleration of the maintenance forecast may cause the output to repeatedly go ON/OFF. Only the S8VS-09024A@@, S8VS-12024A@, S8VS18024A@, S8VS-24024A@, and S8VS-48024A are equipped with output. 

   **4.** The accuracy of the maintenance forecast function may be adversely affected by applications in which the AC input is frequently turned ON/OFF. 

## **Reference Values (15-W to 480-W Models)** 

|**Item**|**Value**|**Definition**|
|---|---|---|
|Reliability<br>(MTBF)|15 W to 240 W:<br>135,000 hr min.<br>480 W:<br>60,000 hr min.|15 W to 240 W:<br>MTBF stands for Mean Time<br>Between Failures, which is<br>calculated according to the<br>probability of accidental device<br>failures, and indicates reliability of<br>devices.<br>Therefore, it does not necessarily<br>represent the life of the Product.|
|Life<br>expectancy|expectancy 10 yr min.|The life expectancy indicates<br>average operating hours under the<br>ambient temperature of 40°C and a<br>load rate of 50%. Normally this is<br>determined by the life expectancy of<br>the built-in aluminum electrolytic<br>capacitor.|



- **Note:** The maintenance forecast is the service life (the power supply’s internal temperature is monitored at all times) of the internal electrolytic capacitor in actual operating conditions, and varies according to the customer’s operating conditions. 15 years is taken as the maximum period of the maintenance forecast.

- **Note: 1.** The total run time does not include the time that the Power Supply is OFF. 

   **2.** The total run time measures the total time that power is being supplied and is not related in any way to deterioration in the electrolytic capacitor built into the Power Supply or to the effects of the ambient temperature. 

The accumulated value of the operating time of the Power Supply is displayed as the total run time. 0 (kh) will be displayed initially after purchase and then the display will advance in 1-kh steps as the operating time accumulates. When the total run time reaches the alarm set value, the alarm (a02) and the total run time will be displayed alternately and a transistor (total run time output terminal (kh)) will output the status externally. 

(Alarm set value reached = OFF, i.e., no continuity at the total run time output terminal (kh)) 

The alarm set value can be changed in the setting mode. The S8VS-09024BE@, S8VS-12024BE, S8VS-18024BE, and S8VS24024BE do not have an alarm output.

**15-W and 30-W Models** 

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

- Use a mounting bracket when the Product is mounted facing horizontally. 

- Heat dissipation will be adversely affected. When the Product is mounted facing horizontally, always place the side with the label facing upward. 

- Operate the Power Supply within a range that is 5°C less than the values in the derating curve in _Engineering Data_ on page 18 if the Power Supply is used with an installation spacing of 10 mm min. (20 mm max.) on the left and right. 

## **60-W, 90-W, 120-W, 180-W, 240-W, and 480-W Models** 

- Improper mounting will interfere with heat dissipation and may occasionally result in deterioration or damage of internal parts. Use the standard mounting method only. 

- The internal parts may occasionally deteriorate and be broken due to adverse heat radiation. Do not loosen the screw on the side face of the main body. 

## **Wiring** 

- Connect the ground completely. A protective earthing terminal 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 Product for machining before power-ON so that it does not interfere with heat dissipation. 

- When wiring a screwless terminal block, do not insert more than one wire into a single terminal. 

- When using a screwless terminal block, connect or disconnect the I/O wire to each terminal while inserting an appropriate tool, such as a flat-blade screwdriver, into the tool insertion hole. Make sure that the wire is securely connected to the terminal after wiring. Do not insert wires into the tool insertion holes. 

If a wire is not inserted far enough or if it is loose, electric shock, fire, or equipment failure may occur. Strip the wires according to specifications. Insert an appropriate tool, such as a flat-blade screwdriver, into the tool insertion hole, insert the wire until the stripped portion is no longer visible, and then remove the tool. Make sure that the wires are securely connected to the terminal block after wiring. Never insert wires into the tool insertion holes.

## **Safet Precautions y** 

- Strip I/O wires for 11 mm when using a screwless terminal block. 

- * The rated current for output terminals is 10 A per terminal. Be sure to use multiple terminals simultaneously for current that exceeds the terminal rating. When applying a current of 10 A or more, use at least two terminals each for the positive and negative wires. 

## **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, high-frequency 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 cut in half 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%. 

- Do not use the Power Supply in areas outside the derating curve otherwise, internal parts may occasionally deteriorate or be damaged. 

- Use the Power Supply at a humidity of 25% to 85%. 

- Do not use the Power Supply in locations subject to direct sunlight. 

- Do not use locations where liquids, foreign matter, or corrosive gases may enter the interior of Products. 

## **S8VS-** @@@ **24A** @@ **Models only** 

Satisfy the following conditions when storing the Power Supply for long periods of time to maintain its remaining service life function. When storing for more than three months, store within an ambient temperature range of −25 to +30°C and the humidity range of 25% to 70%. 

## **Periodic Check for Models with Indication Monitor Except 60-W Models** 

It may take from several years to more than 10 years under general operating conditions for the power supply to output the maintenance forecast monitor alarm (S8VS-@@@24A@@). The total run time monitor (S8VS-@@@24B@@/S8VS-@@@24BE@) may be a similar number of years as the maintenance forecast monitor according to some settings. During operation over an extended period of time, periodically check if the maintenance forecast monitor output (Yrs) or total run time monitor output (kh) is correctly functioning by the following procedure. 

**1.** Select the operation mode. 

**2.** Check that the output (Yrs/kh) is turned ON (with continuity). 

**3.** In the operation mode, press and hold the Down Key D (10) and the Mode Key M (8) simultaneously for at least three seconds. The main display (6) changes to “a02.” 

   - An inactive output (Yrs/kh) (no continuity) in the “a02” indication indicates the correct function. 

**4.** Release keys to return to the regular state. 

**Note:** DC output stays ON during the periodical check.

## **Overcurrent Protection** 

- Internal parts may possibly deteriorate or be damaged if a short-circuited or overcurrent state continues during operation. 

- Internal parts may possibly deteriorate or be 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. 

- The DC ON indicator (green) flashes if the overload protection function operates. 

## **Alarm Output for Models with Indication Monitor Except 60-W and BE Models** 

When using the alarm output, sufficiently consider the maximum ratings, residual voltage, and leakage current. Transistor output: Sinking for S8VS-24A@/@@@24B@ models Sourcing for S8VS-@@@24AP@/@@@24BP@ models 

Sinking/Sourcing for S8VS-48024A/B models 30 VDC max., 50 mA max. ON residually voltage:2 V max. OFF leakage current: 0.1 mA max.

- 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. 

## **15-W, 30-W Models** 

- If the output voltage is set to a value less than −10%, the undervoltage alarm function may operate. 

- Depending on the model, internal circuits may be damaged due to startup failure when the power is turned ON if loads such as a servomotor or operational amplifier may operate in series. Therefore, connect bypass diodes (D1, D2) as shown in the following figure. 

## **60-W, 90-W, 120-W, 180-W, 240-W, and 480-W Models** 

- If the detection voltage of the undervoltage alarm function is at the factory setting and the output voltage is set to a value of 20 V or less, the undervoltage alarm function may operate. 

If the list of models that support series connection of outputs says that an external diode is not required, an external diode is also not

## **Backup Operation** 

- Backup operation can be performed. Backup operation provides protection by using an extra Power Supply even if the output current is sufficient with one Power Supply. If one of the Power Supplies fails, the second Power Supply still provides sufficient

   - Use the same model for Power Supplies A and B. 

   - • Use a load capacity that can be supplied by either Power Supply A or Power Supply B alone. 

**3.** Serial operation is not possible with 5-V and 12-V models. 

## **Making Positive/Negative Outputs** 

   - If backup operation is used, be sure to connect a diode to both Power Supply A and Power Supply B as shown in the above figure so that the backup Power Supply is not affected by a failed Power Supply. 

- The outputs are floating outputs (i.e., the primary circuits and secondary circuits are separated). You can therefore make positive and negative outputs by using two Power Supplies. You can make positive and negative outputs with any of the models. 

Use the following information as a guide to the diode type, dialectic strength, and current. 

- If positive and negative outputs are used, connect Power Supplies of the same model as in the following figure. (Combinations with different output capacities or output voltages can be made.

## **Safet Precautions y** 

- ~~Type: Schottky barrier diode~~ 

- Dielectric strength (VRRM): Rated Power Supply output voltage or higher 

- Forward current (IF): Twice the rated Power Supply output current or higher 

- Increase the output voltage setting of Power Supply A and Power Supply B by the drop in the forward voltage (VF) of diodes D1 and D2. 

Also, the diodes will cause a power loss equivalent to the Power Supply output current (IOUT) times the diode forward voltage (VF). Therefore, cooling measures must be implemented so that the temperature of the diodes decreases to the catalog value or lower. 

- Because of the load power and power loss due to the diodes, do not exceed the rated power of one Power Supply (rated output voltage x rated output current). 

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

The possible cause for no output voltage may be that the overcurrent or overvoltage protection has operated. The internal protection may operate if a large amount of surge voltage such as a lightening surge occurs while turning ON the power supply. 

In case there is no output voltage, please check the following points before contacting us: 

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

- Checking overvoltage or internal protection: 

Turn the power supply OFF once, and leave it OFF for at least 

- 3 minutes. Then turn it ON again to see if this clears the condition. 

## **Audible Noise at Power ON** 

## **(120-W, 180-W, 240-W, and 480-W Models)** 

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