The DRR-20☐ and DRR-40☐ can operate over a wide temperature range of -40°C to -80°C. The state-of-the-art design is made to withstand harsh industrial environments. The rugged, compact aluminium case is shock and vibration resistant according to IEC 60068-2 standard. Due to the wide input and output voltage range from 22 Vdc to 60 Vdc, the redundancy modules are able to support power supply in parallel operation. These modules also have an alarm relay contact as an indicator.

If the output capacity is not reduced when the surrounding air temperature exceeds its specification as defined on Page 3 under “Environment”, the device may have some thermal stress problem and the ORing Diodes may become too hot. 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. Assembly & Installation The unit can be mounted on 35 mm (1.38 inch) DIN rails in accordance with EN 60715. The device should be installed with input terminal block at the top. Each device is delivered ready to install. Mounting Dismounting Fig. 2.1 Mounting Fig. 2.2 Dismounting 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. To uninstall, pull or slide down the latch with screw driver as shown in Fig. 2.2. Then slide the unit in the opposite direction, release the latch and pull out the unit from the rail. In accordance to UL 60950 and EN 62368 / UL 62368, flexible cables require ferrules. Use appropriate copper cables designed to sustain operating temperature of 60°C / 75°C or more to fulfill UL requirements. 9 All parameters are specified at 25°C ambient and AC input unless otherwise indicated. www.DeltaPSU.com (August 2022, Rev. 09.1) TECHNICAL DATASHEET CliQ II Redundancy Modules 20 A / DRR-20□, 40 A / DRR-40□ Safety Instructions Horizontal Mounting  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, please refer to the following instructions to ensure sufficient clearance around the device. Vertical Mounting: 50 mm (1.97 inch) above and below the device as well as a lateral distance of 20 mm (0.79 inch) to other units. Horizontal Mounting: 50 mm (1.97 inch) above and below the device as well as a lateral distance of 50 mm (1.97 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 supply of the unit shall comply with any isolated secondary circuit according to UL 508, Clause 32. • • • • • •  For DRR-20A and DRR-40A: • The unit must be installed in an IP54 enclosure or cabinet in the final installation. The enclosure or cabinet must comply with EN 60079-0 or EN 60079-15. • Warning: Explosion Hazard - Substitution of components may impair suitability for Class I, Division 2. • Warning: Explosion Hazard - Do not disconnect equipment unless the power has been switched off or the area is known to be nonhazardous. 10 All parameters are specified at 25°C ambient and AC input unless otherwise indicated. www.DeltaPSU.com (August 2022, Rev. 09.1) TECHNICAL DATASHEET CliQ II Redundancy Modules 20 A / DRR-20□, 40 A / DRR-40□ Functions Typical Application Notes Fig. 3.1 1+1 Redundancy Fig. 3.2 Single Use Using 1 more PSU as the redundant unit.

Follow simple steps given below to set them up for the redundant operation: Step 1. Measure output voltage of PSU 1 and PSU 2. If PSU 1 is the master unit, then VO of PSU 1 must be higher than PSU 2. In order to set the output voltage, individually connect the power supply to 50% of rated load at any line voltage, and set the PSU 1 and PSU 2 output voltage. Step 2. Connect the right DRR module as per the system requirement to the power supply units PSU 1 and PSU 2 at Vin 1 & Vin 2 respectively 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). **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. 4 Redundant / Parallel Operation Connection Diagram *Vdrop will vary from 0.60 V to 0.90 V (Typical 0.65 V) depending on the load current and surrounding air temperature.  Parallel Operation These DRR modules can also be used for Parallel function in order to increase the output power by N+1 (e.g. 2.5 A + 2.5 A = 5 A or 2.5 A + 2.5 A + 2.5 A = 7.5 A) or current sharing, and thus increasing the power supply and system reliability. A good current sharing between two power supplies can be achieved by following simple steps as below (Refer to Fig. 4 for the 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 ±25 mV difference. 12 Step 3. Connect PSU 1 and PSU 2 with the DRR module and measure at Vin 1 & Vin 2 to verify the voltage difference. Ensure the voltages are within ±25 mV. Step 4. Output voltage from DRR module Vout will be = VO (output voltage of power supply) – Vdrop* (in DRR module). All parameters are specified at 25°C ambient and AC input unless otherwise indicated. www.DeltaPSU.com (August 2022, Rev. 09.1) TECHNICAL DATASHEET CliQ II Redundancy Modules 20 A / DRR-20□, 40 A / DRR-40□ 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.
