The DRB960-48-3-A7 is a 960W, 48VDC DIN rail-mounted power supply with push-in terminals, designed for industrial automation, renewable energy, and communications applications. It operates from AC input ranges of 342-575VAC or DC input of 450-810VDC, with an output voltage adjustable from 45 to 56VDC and a nominal output current of 20A. Boost current of up to 30A is available for 5 or 7 seconds to support heavy start-up loads. Efficiency exceeds 95.8% under AC input and 96.2% under DC input, with no-load consumption below 7.1W. It features DC-OK and inhibit relay contacts, integrated GDT for surge protection, and complies with IEC EN 61010-1, IEC EN 62368-1, and UL CSA standards. Dimensions are 100 x 129 x 171.9mm, and it operates from -25°C to +70°C. The unit meets EU Low Voltage, EMC, RoHS, and China RoHS regulations.
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.
