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 > 55°C, the device may run into Over Temperature Protection. When activated, the output voltage will go into latch- off mode and recoverable by AC power recycle. 3. In order for the device to function in the manner intended, it is also necessary to keep a safety distance of 25mm with adjacent units 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 do not hesitate to contact info@deltapsu.com for more details.

Input Voltage 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  No output power de -rating across the entire input voltage range Dismounting Fig. 2.1 Mounting Snap on the DIN rail as shown in Fig. 2.1: 1. Tilt the unit upwards and insert it onto the DIN rail. 2. Push downwards until stopped. 3. Press against the bottom front side for locking. 4. Shake the unit slightly to ensure that it is secured. Fig. 2.2 Dismounting To uninstall, pull or slide down the latch with screw driver as shown in Fig. 2.2. Then slide the power supply unit (PSU) in the opposite direction, release the latch and pull out the power supply unit (PSU) from the rail.

Rise Time The time required for the output voltage to change from 10% to 90% of its set value. Hold-up Time Hold up time is the time when the AC input collapses and output voltage retains regulation for a certain period of time. The time required for the output to reach 90% of its set value, after the input voltage is removed. – 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 above and below the device as well as a lateral distance of 25mm 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! – 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 unit should be installed in minimum IP54 rated enclosure. – The power supplies are built in units and must be instal led in a cabinet or room (condensation free environment and indoor location) that is relatively free of conductive contaminants.

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 10 to 100% of its rated current. Overvoltage Protection 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 3 under “Protections”. Overload & Overcurrent Protections The power supply’s Overload (OLP) and Over current (OCP) Protections will be activated when output current exceeds 110% of IO (Max load). In such occurrence, once the power supply has reached its maximum power limit, the protection is activated and the power supply will go into “Hiccup mode” (Auto-Recovery). The power supply will recover once the fault condition of the OLP and OCP is removed and IO is back within the specifications. Over Temperature Protection As mentioned above, 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 latch-off mode until the component temperature cools down and the AC power is recycled. Short Circuit Protection The power supply’s output OLP/OCP function also provides protection against short circuits. When a short circuit is applied, the output current will operate in “Hiccup mode”, as shown in the illustration in the OLP/OCP section on this page. The power supply will return to normal operation after the short circuit is removed.

Follow simple steps given below to verify: Step 1. Measure output voltage of PSU 1 and PSU 2. If PSU 1 is the master unit, then V O of PSU 1 must be higher than PSU 2. In order to set the output voltage, connect the power supply to 50% load and set the PSU 1 and PSU 2 output voltage. Step 2. Connect the right DRR module, 20A as per the system requirement to the power supply units PSU 1 and PSU 2 at V in 1 & V in 2 respectively. Step 3. Connect the system load from V out. Please note that output voltage V out from DRR module will be = V O (output voltage of power supply) – Vdrop* (in DRR module).  Parallel Operation + 2.5A + 2.5A = 7.5A) or current sharing, and thus increasing the power supply and system reliability. Though the DRC -24V60W1AZ is not designed for current sharing, a good current sharing between two power supplies can be achieved by following simple steps as below (Refer to Fig. 3 for the Connection Diagram). Fig. 3 Redundancy / Parallel Operation Connection Diagram Step 1. Set output load condition for both supplies at 50% and measure the output voltages. Step 2. Adjust output voltages to the same level or within ±25mV difference. Step 3. Connect PSU 1 and PSU 2 with the DRR -20A module and measure at Vin 1 & Vin 2 to verify the voltage difference. Ensure the voltages are within ±25mV. Step 4. Output voltage from DRR module V out will be = V O (output voltage of power supply) – Vdrop* (in DRR module). *Vdrop will vary from 0.60V to 0.90V (Typical 0.65V) depending on the load current and surrounding air temperature.
