The DRB480-24-3-A6 is a 480W, 24VDC DIN-rail power supply with screw terminals and conformal coating for use in corrosive environments. It operates from AC input voltages of 300-575VAC or DC input voltages of 390-810VDC, with a nominal output current of 20A and boost capability up to 30A for 5 or 7 seconds. It achieves 95.1% efficiency under AC input, with a power factor of 0.92 and no-load consumption under 3.2W. The unit includes DC-OK and inhibit relay contacts, integrated GDT for surge protection, and meets IEC EN 61010-1, IEC EN 62368-1, and UL CSA standards. It complies with EU Low Voltage, EMC, RoHS, and Hazardous Substances Directives. Dimensions are 65 x 129 x 159.3mm and weight is 1050g. Operating temperature ranges from -25°C to +70°C, with a minimum MTBF of 4.40 million hours at 50% load. Parallel operation and load balancing are supported via a switch.
The DIN-Rail power supplies in the DRB series are part of TDK-Lambda’s industrial heritage. They can be used in many applications, ranging from conventional switch cabinets and decentralised machinery and systems, to renewable energy and charging solutions. The series covers the popular output voltages of 12, 24, 48 and 72 volts, and users can operate them, both with AC or DC voltage.
The DRB’s high operating efficiencies, the use of high-quality electrolytic capacitors and the integration of a gas discharge tube provide maximum system up-time.
Special models featuring conformal coating are available for use in challenging environments containing corrosive gases. Overall the DRB 3 phase series offer an excellent balance between functionality and price.
