The DRB960-48-3-A1 is a 960 W DIN-rail power supply with a 48 VDC output, designed for industrial automation, renewable energy, and communications applications. It supports both AC input (342-575 VAC) and DC input (450-810 VDC), with a wide operating temperature range of -25 to +70 °C. The unit features push-in terminals for simplified wiring, a 30 A boost current capability for 7 seconds, and integrated relay contacts for DC-OK and inhibit signals. It achieves typ. 95.8% efficiency under AC input and meets IEC EN 61010-1, IEC EN 61010-2-201, and IEC EN 62368-1 safety standards, along with EU directives for low voltage, EMC, RoHS, and hazardous substances. Physical dimensions are 100 × 129 × 171.9 mm, with a weight of 1750 g.
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.
