## **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. 1. 

2. If the output capacity is not reduced when the surrounding air temperature > 40°C (115Vac) or > 50°C (230Vac), the device will run into Over Temperature Protection. When activated, power supply will latch off, until the surrounding air temperature is lowered or the load is reduced as far as necessary to keep the device in working condition, and require removal/re-application of input AC voltage in order to restart. 

3. 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. 

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

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

## **Assembly & Installation** 

The power supply unit (PSU) can be mounted on 35mm DIN rails in accordance with EN 60715. The device should be installed with input terminal block at the bottom. 

Each device is delivered ready to install. 

## Mounting 

## **Fig. 2.1  Mounting** 

Snap on the DIN rail as shown in Fig. 2.1: 

1. Pull the unit’s DIN rail latch OUT. 

2. Tilt the unit slightly upwards, hook the top end onto the DIN rail and push downwards until stopped.

## **Fig. 2.2  Dismounting** 

To uninstall, 

   1. Pull the unit’s DIN rail latch OUT. 

   2. Tilt the bottom part of the unit out. 

   3. Push the unit up and pull out from the DIN rail. 

3. Position the bottom front end against the DIN rail. 

4. Push the unit’s latch DIN rail IN to lock. 

In accordance to EN 60950 / UL 60950 and EN 62368 / UL 62368, flexible cables require ferrules. 

Use appropriate copper cables designed to sustain operating temperature of at least 60°C / 75°C or more to fulfill UL requirements. 

## Safety Instructions 

- **Vertical Mounting** 

- ALWAYS switch mains of input power OFF before connecting and disconnecting the input voltage to the unit. If mains are not turned OFF, there is risk of explosion / severe damage. 

- **To guarantee sufficient convection cooling, keep a distance of 50mm (1.96 inch) above and below the device as well as a lateral distance of 10mm (0.39 inch) to other units.** 

- Note that the enclosure of the device can become very hot depending on the surrounding air temperature and load of the power supply. Risk of burns! 

- The main power must be turned off before connecting or disconnecting wires to the terminals. 

- • DO NOT insert any objects into the unit. 

- Hazardous voltages may be present for up to 5 minutes after the input mains voltage is disconnected. Do not touch the unit during this time. 

- The power supplies are built in units and must be installed in a cabinet or room (condensation free environment and indoor location) that is relatively free of conductive contaminants. 

All parameters are specified at 25°C ambient and AC input unless otherwise indicated. **www.DeltaPSU.com (January 2021, Rev. 02)**

## **Functions** 

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

## Start-up Time 

The time required for the output voltage to reach 90% of its final steady state set value, after the input voltage is applied. 

## Rise Time 

The time required for the output voltage to change from 10% to 90% 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 ±10% of its steady state value, when subjected to a dynamic load from 0% to 50% and 50% to 100% of its rated current. 

- **50% duty cycle / 5Hz to 100Hz**

**TECHNICAL DATASHEET** 

## **LYTE DIN Rail Power Supply** DRL-75W series / DRL- □ V75W1AZ 

## Overload & Overcurrent Protections (Continuous Current) 

The power supply’s Overload (OLP) and Overcurrent (OCP) Protections will be activated when output current is 105~133% of IO (Max load). Upon such an occurrence, the VO (output voltage) will start to droop. Once the power supply has reached its maximum power limit, the protection will be activated; and, the power supply will operate in continuous current. The power supply will recover once the cause of OLP or OCP is removed, and IO (output current) is back within the specified range. 

## Overvoltage Protection (Latch Mode) 

The power supply’s overvoltage circuit will be activated when its internal feedback circuit fails. The output voltage shall not exceed its specifications as described in “Protections” section. Power supply will latch off, and require removal/re-application of input AC voltage in order to restart. 

## **The power supply should be latch.** 

## Over Temperature Protection (Latch Mode) 

## 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 operate in “Hiccup mode”. The power supply will return to normal operation after the short circuit is removed. 

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; or, when the operating temperature is beyond what is recommended in the de-rating graph, the OTP circuit will be activated. When activated, power supply will latch off, until the surrounding air temperature drops to its normal operating temperature or the load is reduced as recommended in the de-rating graph. Removal/re-application of input AC voltage will then be required in order to restart.
