The buffer module utilizes maintenance-free electrolytic capacitors to store energy, thus eliminates the need of periodic replacement as compared to costlier batteries which also have shorter functional life span. The DRB-24V020AB☐ comes with comprehensive protection features like overvoltage, over current and short circuit protections. The rugged compact aluminium case is shock and vibration resistant according to IEC 60068-2 standard.

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 unit is a built-in unit and must be installed in a cabinet or room (condensation free environment and indoor location) that is relatively free of conductive contaminants. • • • • • •  For DRB-24V020ABA: • 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 or adjust switch unless the power has been switched off or the area is known to be non-hazardous. 9 All parameters are specified at 25°C ambient and AC input unless otherwise indicated. www.DeltaPSU.com (November 2021, Rev. 06) TECHNICAL DATASHEET CliQ II Buffer Module 24 V 20 A / DRB-24V020AB□ Functions Buffering, Ready and Inhibit Signal Characteristics Signal Level Low: < 1 V; High: < +VS-2 V Supply Voltage (+VS) Min = 10 Vdc, Max = 35 Vdc Maximum Signal Output 35 V / 10 mA Buffering Signal (B) “High” = Buffer module is discharging or in buffering mode Isolation (Signal Port to Power Port) 1.5 KVac LED Indicator Green LED Flashing Quickly (10Hz) Ready Signal (R) “High” = Buffer module is fully charged or in standby mode Isolation (Signal Port to Power Port) 1.5 KVac LED Indicator Green LED On Inhibit Signal (I) “Low” = Shuts down buffer module Shut-down Threshold 6 Vdc Min / 10 Vdc Max Isolation (Signal Port to Power Port) 1.5 KVac Operating Diagram Wiring Schematics Typical Application Notes can be found on Page 9. 10 All parameters are specified at 25°C ambient and AC input unless otherwise indicated. www.DeltaPSU.com (November 2021, Rev. 06) TECHNICAL DATASHEET CliQ II Buffer Module 24 V 20 A / DRB-24V020AB□ Typical Application Notes Fig. 4.1 General connection / wiring diagram Fig. 4.2 Paralleling of buffer units Fig. 4.3 Decoupling of buffered branches Fig. 4.4 General signals wiring Fig. 4.5 Signals supplied from an external voltage Fig. 4.6 Connection diagram with redundant operation 11 All parameters are specified at 25°C ambient and AC input unless otherwise indicated. www.DeltaPSU.com (November 2021, Rev. 06) TECHNICAL DATASHEET CliQ II Buffer Module 24V 20A / DRB-24V020AB□ Connectable Power Supplies The buffer module is recommended to be connected with the following power supplies: CliQ Series DRP024V060W1AA DRP024V060W1AZ DRP024V120W1AA DRP024V240W1AA DRP024V480W1AA CliQ II Series DRP024V060W1B☐ DRP024V120W1B☐ DRP024V240W1B☐ DRP024V480W1B☐ Inrush Current Overvoltage Protection (Latch Mode) Inrush current is the peak, instantaneous, input current measured and, occurs when the input voltage is first applied. For DC input voltages, the maximum peak value of inrush current will occur during the first applied DC voltage. The buffer module’s overvoltage protection will be activated when DC input to the module exceeds the maximum specified input voltage. The overvoltage limits are same as power supply limits, 32V±10%. Buffer module will shut down and latch during overvoltage mode, and will return to normal operation upon removal of fault and power supply input is recycled (ON/OFF) or input to buffer module is recycled. Short Circuit Protection (Latch Mode) Overload & Overcurrent Protections (Latch Mode) When the output current exceeds 120% of IO (Max load) buffer module will shut down and latch. Normal operation of buffer module can be resumed upon removal of fault and power supply input is recycled (ON/OFF) or input to buffer module is recycled. 12 Buffer module is protected by short circuit during buffering mode, in the event of short circuit the module will shut down and latch. Operation can be resumed upon removal of fault and power supply in put is recycled (ON/OFF) or input to buffer module is recycled.

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.
