TDK-Lambda Corporation 120/960W DIN-Rail power supplies DRB480-72-3-A1

Description
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. Explore the DRB 3 Phase Series Features Operation with AC or DC voltage for a wide range of applications Parallel mode switch to activate load balancing behaviour Integrated GDT for ultimate process stability Very low inrush energy peak (I²t) saves cost for input line protection Screw or push-in terminals available to serve individual application needs High efficiency contributes to an eco-friendly energy footprint DC-OK and inhibit relay contacts for professional integration into applications control architecture Comprehensive boost power capabilities support start-up into heavy loads Exceeds regulatory EMC standards on radiated emission (Class B), surge immunity and fast transients Applications for this product General Purpose Industrial Factory Automation / Process Control Test & Measurement Broadcast / Communications / Professional Audio Renewable Energy Semiconductor Fabrication

Datasheet
Datasheet Summary
Powered by GS/AI

The DRB480-72-3-A1 is a 480W, 72VDC DIN-rail power supply with push-in terminals for input, output, and signaling connections. It operates from AC 300-575V or DC 390-810V, with a nominal output current of 6.7A and a boost current of up to 10A for up to 7 seconds. Efficiency reaches 95.7% under AC input, with no-load consumption under 3.4W. The unit supports parallel operation, includes DC-OK and inhibit relay contacts, and complies with IEC EN 61010-1, IEC EN 61010-2-201, IEC EN 62368-1, UL CSA 61010-1, UL CSA 61010-2-201, and UL CSA 62368-1 standards. It measures 65 × 129 × 159.3mm and weighs 1050g. Installation requires a minimum clearance of 5mm to heat sources and 2mm to passive components. The device exceeds EMC Class B radiated emissions and supports wide ambient operating temperatures from -25°C to +70°C.
