TECHNICAL DATASHEET CliQ II Buffer Module 24V 40A / DRB-24V040ABN Highlights & Features - - - - - Full corrosion resistant aluminium chassis Minimum buffering time of 200ms @ 24V/40A Flexible operating buffering voltage modes: o Fixed mode at 22Vdc o Dynamic mode for Vin -1V Supports parallel connection to extend buffering time Conformal coating on PCBA to protect against chemical and dust pollutants Safety Standards CB Certified for worldwide use Model Number: DRB-24V040ABN Unit Weight: 0.76kg Dimensions (L x W x D): 121 x 70 x 120.1 mm General Description Delta's CliQ II buffer module offers the most widely used output voltage of 24V and a minimum buffering time of 200ms at 40A in wide input range from 22.8Vdc to 28.8Vdc. 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-24V040ABN 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.

In order for the device to function in the manner intended, it is also necessary to keep a safety distance of 20mm (Vertical Mounting) or 50mm (Horizontal Mounting) with adjacent units 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 do not hesitate to contact info@deltapsu.com for more details. TECHNICAL DATASHEET CliQ II Buffer Module 24V 40A / DRB-24V040ABN Assembly & Installation The unit can be mounted on 35mm DIN rails in accordance with EN 60715. The device should be installed with Input / Output terminal block at the top. Each device is delivered ready to install. Mounting Dismounting Fig. 3.1 Mounting Fig. 3.2 Dismounting Snap on the DIN rail as shown in Fig. 3.1: 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. 3.2. Then slide the unit in the opposite direction, release the latch and pull out the unit from the rail. In accordance to EN 60950 / UL 50950, flexible cables require ferrules. Use appropriate copper cables designed to sustain operating temperature of: 1. 60C, 60C / 75C for USA 2. At least 90C for Canada. 7 All parameters are specified at 25C ambient unless otherwise indicated. www.DeltaPSU.com (January 2015, Rev. 00) TECHNICAL DATASHEET CliQ II Buffer Module 24V 40A / DRB-24V040ABN Safety Instructions - - - - - - - 8 Vertical Mounting Horizontal 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 above and below the device as well as a lateral distance of 20mm (Vertical Mounting) or 50mm (Horizontal Mounting) 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. All parameters are specified at 25C ambient unless otherwise indicated. www.DeltaPSU.com (January 2015, Rev. 00) TECHNICAL DATASHEET CliQ II Buffer Module 24V 40A / DRB-24V040ABN Functions Buffering, Ready and Inhibit Signal Characteristics Signal Level Low: < 1V; High: < +VS-2V Supply Voltage (+VS) Min = 10Vdc, Max = 35Vdc Maximum Signal Output 35V / 10mA Buffering Signal (B) "High" = Buffer module is discharging or in buffering mode Isolation (Signal Port to Power Port) 1.5KVac 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) 1.5KVac LED Indicator Green LED On Inhibit Signal (I) Isolation (Signal Port to Power Port) "Low" = Shuts down buffer module 1.5KVac Operating Diagram Wiring Schematics Typical Application Notes can be found on Page 10. 9 All parameters are specified at 25C ambient unless otherwise indicated. www.DeltaPSU.com (January 2015, Rev. 00) TECHNICAL DATASHEET CliQ II Buffer Module 24V 40A / DRB-24V040ABN 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 10 All parameters are specified at 25C ambient unless otherwise indicated. www.DeltaPSU.com (January 2015, Rev. 00) 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 - DRP-24V48W1AA - DRP024V060W1AA - DRP024V060W1AZ - DRP024V120W1AA - DRP024V240W1AA - DRP024V480W1AA CliQ II Series - DRP024V060W1B - DRP024V060W1N - DRP024V120W1B - DRP024V240W1B - DRP024V480W1B - - - - - DRP024V060W3B DRP024V120W3B DRP024V240W3B DRP024V480W3B DRP024V960W3BN Short Circuit Protection Overload & Overcurrent Protections 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. 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. Others Delta RoHS Compliant Restriction of the usage of hazardous substances The European directive 2011/65/EU limits the maximum impurity level of homogeneous materials such as lead, mercury, cadmium, chrome, polybrominated flame retardants PBB and PBDE for the use in electrical and electronic equipment. RoHS is the abbreviation for "Restriction of the use of certain hazardous substances in electrical and electronic equipment". This product conforms to this standard. 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. 11 All parameters are specified at 25C ambient unless otherwise indicated. www.DeltaPSU.com (January 2015, Rev. 00) Mouser Electronics Authorized Distributor Click to View Pricing, Inventory, Delivery & Lifecycle Information: Delta Electronics: DRB-24V040ABA
