## **Safety Standards** 

CB Certified for worldwide use 

**Model Number:** DRM-24V960W3PN **Unit Weight:** 2.30 kg (5.07 lb) **Dimensions (L x W x D):** 124.0 x 110.0 x 128.6 mm (4.88 x 4.33 x 5.06 inch) 

## **General Description** 

Delta Electronics is introducing one of the slimmest DIN rail industrial power supplies in its class, the CliQ M DIN rail power supply series. To fulfill the demands in maritime applications, the product is designed according to major industrial and maritime (Lloyd’s Register) safety standards. Other features include compliance with harmonic current IEC/EN 61000-3-2, class A, built-in DC OK contacts, and an LED for indicating DC OK and Overload conditions. In addition to having Power Boost of 150% up to 7 seconds, the CliQ M series is the first in the CliQ family to feature Advanced Power Boost (APB). With multiple loads connected in a system, a large inrush current could be drawn (demanded) due to one fault load. This will be detected by APB. The APB will trip the circuit breaker (circuit breaker with appropriate rating based on the system load) on the current path of the fault load due to high current. This thus prevents the system from shutting down while the other connected current paths continue to operate without interruption.

Output Load De-rating VS Surrounding Air Temperature 

## **Note** 

1. Power supply components may degrade, or be damaged, when the power supply is continuously used outside the shaded region, refer to the graph shown in Fig. 5. 

2. 

3. 

4. 

5. 

If the output capacity is not reduced when the surrounding air temperature exceeds its specification as defined on Page 5 under “Environment”, the device will run into Over Temperature Protection. When activated, the output voltage will go into bouncing mode and will recover when the surrounding air temperature is lowered or the load is reduced as far as necessary to keep the device in working condition. 

In order for the device to function in the manner intended, it is also necessary to keep a safety distance as recommended in the safety instructions while the device is in operation. 

- Depending on the surrounding air temperature and output load delivered by the power supply, the device can be very hot! 

- If the device has to be mounted in any other orientation, please contact **info@deltapsu.com** for more details.

## **CliQ M DIN Rail Power Supply** 24V 960W 3 Phase / DRM-24V960W3PN 

## Single/Parallel Selection 

This select jumper on the front of the power supply unit (refer to Device Description, item 7 in page 9) enables load sharing when power supplies are connected in parallel. When the jumper is in parallel mode, the output voltage will droop down around 4% from no load to maximum load. If the jumper is not plugged in, the power supply unit functions in single mode. Default factory setting jumper is in single mode. 

**Parallel Selection Single Selection** 

## Instructions for Parallel Mode: 

Ensure that output voltage is adjusted to Vo + 1V (±0.1V) in “Parallel Mode" at no load conditions on all units. Vo = output voltage at maximum load conditions in parallel mode. 

## Example: 

Vo at maximum load = 24V. The output voltage adjusted for parallel mode at no load should be (Vo + 1V) 24 + 1 = 25V (±0.1V). 

## Shut-Down Input Characteristics 

This feature allows a switch-off of the output of the power supply with a signal switch or an external voltage. 

- The shut-down function has no safety feature included. 

- The shut-down occurs immediately while the turn-on is delayed up to 350ms. 

- In a shut-down condition, the output voltage is <2V and the output power is <0.5W. 

- 

   - In a series operation of multiple power supplies only wiring option "A" with individual signal switches is allowed. 

- Please note that option C requires a current sink capability of the voltage source. Do not use a blocking diode. 

- In option C the PSU should be ON at U = 4 to 29V ± 0.5V

## Instructions: 

- Set the unit into “Single mode”. 

- 

   - Set the output voltage adjustment to the maximum desired voltage. 

- Apply a control voltage to reduce the output voltage. 

## Internal Data Logging 

A protected microcontroller inside the power supply acquires and stares operating data during the life of the unit. The data can be downloaded with a small tool and special software by the Delta service and repair personnel even when the unit is defect. The data allows for better troubleshooting. Analysis of what happened before a failure can be determined much more accurately. Acquired data: 

- Family name of unit (M24V960W3PN), revision of firmware 

- Operational hours 

- Expired portion of lifetime (combination of temperature and period of time) 

- Maximal input voltages with timestamp (max 19 values) 

- Number of phase AC-input 

- AC and DC input type 

- Maximal AC input voltages with timestamp (max 19 values) 

- Failure report (various internal errors) 

- Number and timestamp of input overvoltage transients 

- Number and timestamp of over-temperature shut- downs 

- Number of turn-on sequences 

The data will be acquired with a fixed sampling rate unless the peak detectors do trigger due to an abnormal condition. In such cases, the abnormal condition will be captured. Furthermore, data will be acquired every time shortly before the unit switches off.

## **CliQ M DIN Rail Power Supply** 24V 960W 3 Phase / DRM-24V960W3PN 

##  **Graph illustrating the Start-up Time, Rise Time, and Hold-up Time** 

## Start-up Time 

The time required for the output voltage before output voltage rise up, after the input voltage is applied. 

## Rise Time 

The time required for the output voltage to change from 0% to 95% of its final steady state set value. 

## Hold-up Time 

Time between the collapse of the AC input voltage, and the output falling to 95% of its steady state set value. 

## Inrush Current 

Inrush current is the peak, instantaneous, input current measured and, occurs when the input voltage is first applied. For AC input voltages, the maximum peak value of inrush current will occur during the first half cycle of the applied AC voltage. This peak value decreases exponentially during subsequent cycles of AC voltage. 

## Dynamic Response 

The power supply output voltage will remains within ±5% of its steady state value, when subjected to a dynamic load from 1.5% to 100% of its rated current. 

- **50% duty cycle / 5Hz to 1KHz**

**TECHNICAL DATASHEET** 

## **CliQ M DIN Rail Power Supply** 24V 960W 3 Phase / DRM-24V960W3PN 

## Overvoltage Protection (Auto-Recovery) 

The power supply’s overvoltage circuit will be activated when its internal feedback circuit fails. The output voltage shall not exceed its specifications defined on Page 6 under “Protections”. 

## Short Circuit Protection (Auto-Recovery) 

The power supply’s output Short Circuit Protection function also provides protection against short circuits. When a short circuit is applied, the output current will start to operate in “Hiccup mode”. The power supply will return to normal operation after the short circuit is removed. 

## Overload & Overcurrent Protections (Auto-Recovery) 

The power supply’s Overload (OLP) and Overcurrent (OCP) Protections will be activated when output current (IO) is >150% of maximum rated load (IO Max). When this occurs, the output current will limit to 42A typ. (refer to Ⓐ below) and output voltage (VO) will start to droop. Once VO is below approximately 20Vdc typ., the power supply will start to operate in “Hiccup mode” as described in short circuit protection. The power supply will recover once the fault condition due to OLP or OCP is removed, then IO is back within its specified limits. 

## Line Input Over Voltage Surge (Auto-Recovery) 

The power supply’s input over voltage protection will be activated when input voltage exceeds 3 x 635Vac. In such occurrence, the power supply will shut down output voltage (VO). The power supply will recover once the input voltage is decreased to lower than 3 x 600Vac and VO shall be back within the specifications. 

## Over Temperature Protection (Auto-Recovery) 

As described in load de-rating section, the power supply also has Over Temperature Protection (OTP). In the event of a higher operating temperature at 100% load, the power supply will run into OTP when the operating temperature is beyond what is recommended in the de-rating graph. When activated, the output voltage will go into bouncing mode until the temperature drops to its normal operating temperature as recommended in the de-rating graph.

## Power Boost 

Power Boost is the reserve power available constantly that allows reliable startup to support sudden and short spike of loads with high inrush current typically during turn on to remove the need of more expensive higher rated power supply unit. After the output has reached its steady state set value, the power supply can support surge loads with a higher short-term power demand up to 150% of maximum rated load (IO Max), for a maximum duration of 7 seconds. If the power boost lasts longer than maximum duration, the output current will limit to 42A typ. and VO (output voltage) will start to droop, refer to the details in overload & overcurrent protections and the next Power Boost will be available after power boost recovery time defined on Page 4. In order to avoid this, need to maintain the duty cycle & recovery time to ensure that average (R.M.S) output power shall not exceed the continuous maximum, see duty cycle calculation below.

## Advanced Power Boost (APB) 

With multiple loads connected in a system and due to one of fault load a large inrush current is drawn (demanded), this will be detected by APB. This APB can trip the external output protection device with appropriate rating based on system load. Thus preventing the system from shutting down while other connected current paths continue to operate without interruption.

## External Input Protection Device 

The unit is protected at the L pin, with an internal fuse that cannot be replaced. The power supply has been tested and approved on 20A (UL) and 16A (IEC) branch circuits without additional protection device. An external protection device is only required if the supplying branch has an ampacity greater than above. Thus, if an external protective device is necessary, or, utilized, please refer a minimum value in instruction sheet with 6A B- or C- characteristic breaker.

## Operating Mode 

##  **Redundant Operation** 

In order to ensure proper redundant operation for the power supply units (PSUs), follow simple steps given below to set them up for the redundant operation: 

## **Step 1.** 

In order to set the output voltage, ensure that each power supply is selected in “Parallel Mode" at no load conditions at any line voltage from 3 x 320-575Vac, and set the PSU 1 and PSU 2 output voltage to Vo* + 1V (±0.1V). 

## **Step 2.** 

Connect the right DRR module, 40A as per the system requirement to the power supply units. PSU 1 should be connected to DRR Module 1 at Vin 1 and Vin 2, and PSU 2 should be connected to DRR Module 2 at Vin 1 & Vin 2 as shown on the Fig 9. 

## **Step 3.** 

Connect the system load from Vout. Please note that output voltage Vout from DRR module will be = VO (output voltage of power supply) – Vdrop** (in DRR module). 

*Vo = output voltage at maximum load conditions in parallel mode 

**Vdrop will vary from 0.60V to 0.90V (Typical 0.65V) depending on the load current and surrounding air temperature. 

***The Signal GND in the DRR module is for the built-in LED and DC OK signals. The Output GND terminals from the two PSU’s do not need to be connected to the Signal GND terminal. 

## **Fig. 9 Redundant Operation Connection Diagram** 

##  **Parallel Operation** 

The power supply units (PSUs) can also be used for parallel operation in order to increase the output power. The output voltage of each power supply shall be adjusted to the same value. In order to set the output voltage, ensure that each power supply is selected in “Parallel Mode" at no load conditions at any line voltage from 3 x 320-575Vac, and set the PSU 1 and PSU 2 output voltage to Vo* + 1V (±0.1V). 

If more than three units are connected in parallel, a fuse or circuit breaker with a rating of 50A or 63A is required on each output. Alternatively, a diode or DRR Module can also be utilized. 

Parameters such as EMI, inrush current, leakage current, PARD, start up time will be different  from those on the datasheet, when two units are connected in parallel. The user will need to verify that any differences will still allow the two power supplies connected in parallel will work properly in their product/application.

**Fig. 11     Series Operation Connection Diagram** 

##  **Series Operation** 

Delta's CliQ M can be connected in series to increase the output voltage as shown in figure above. Only power supply from the same product series, and with the same rated output current, can be used. The maximum load current should not exceed the smallest rated output current. Any number of power supplies can be connected in series. User must note that an output voltage > 60Vdc will not meet SELV requirements and could be dangerous to user, the total voltage shall not exceed 150Vdc. Installation a protection against the touching is a must and connect the output ground to earth when output voltage is not SELV. A diode in reverse bias must be added across output terminals of each power supply, this is to prevent -V voltage being applied to other power supply in fault conditions such as short circuit across load. During the short circuit -V1 & +V1 will come across +V2 & -V2 which means connecting 2 power supplies in opposite polarity and may cause damage to power supply. With reverse bias diodes in place the voltage across each power supply will be restricted to one diode drop – approximately 0.7V to 1.0V. It is recommended to provide sufficient voltage de-rating for diodes with 2 times the voltage rating of series output voltage. E.g. the two 24V power supplies are connected in series, the total voltage is 48 volts. Hence, recommended to use diodes with reverse voltage rating of 2x48=96 volts. Therefore diodes with reverse voltage rating of 100 volts can be used. 

During the short circuit condition, the current through diodes will be large, hence it is recommended that diodes to be least twice the current rating of the power supply. 

The turn ON would be non-monotonic as the power supply with the fastest startup time and rise time will turn on first. As a result, the combined output voltage waveform of the 2 power supplies connected in series will include a step. 

User must consider to verify parameters such as EMI, inrush current, leakage current, PARD, start up time would differ from datasheet numbers as multiple power supplies in series.

## **Others** 

## Conformal Coating 

## **The Protective Coating Technology** 

Delta Electronics Group has designed the perfect dipping technique which penetrates everywhere including under device, and prevents leakage. The conformal coating dipping can be applied to PCBAs or circuit board. The coating preserves the performance of precision electronic primarily by preventing ionizable contaminants such as salt from reaching circuit nodes, where the material slumps around sharp edges. This can be a problem especially in highly conversing atmosphere. 

## PFC – Norm EN 61000-3-2 

## **Line Current Harmonic content** 

Typically, the input current waveform is not sinusoidal due to the periodic peak charging of the input capacitor. In industrial environments, compliance with EN 61000-3-2 is only necessary under special conditions. Complying to this standard can have some technical drawbacks, such as lower efficiency; and, can also result in higher product cost. Frequently, the user does not profit from compliance to this standard; therefore, it is important to know whether it is mandatory to meet this standard for a specific application.
