The DRB480-48-3-A1 is a 480W DIN-rail mounted power supply designed for industrial applications, delivering 48VDC at up to 10A nominal current with a boost capability of 15A for up to 7 seconds. It supports input voltages from 300 to 575VAC or 390 to 810VDC, and operates with 95.9% efficiency under DC input. The unit features push-in terminals for simplified wiring, integrated GDT for surge protection, DC-OK and inhibit relay contacts, and complies with IEC EN 61010-1, IEC EN 61010-2-201, and IEC EN 62368-1 safety standards as well as EU Low Voltage and EMC Directives. Dimensions are 65mm wide, 129mm high, and 159.3mm deep, with a weight of 1050g. It operates within a temperature range of -25°C to +70°C and meets Class B EMC radiated emission limits.
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.
