120% Power Boost for 2 Critical Seconds: Meet the New Addition of the DRB Series

TDK-Lambda is introducing the addition of three-phase AC input models to the DRB series DIN-Rail mount power supplies. The units have a special feature that enables a power boost of 120% for 2 seconds - to support capacitive loads start-up. Their continuous operation is at 120W and 240W; and in peak power they can deliver 144W and 288W. The models have a wide adjustment range of 11.4 to 15V, (12V model), 22.5 to 29V (24V models) and 45 to 56V (48V model). These power supplies also feature a very low energy inrush current upon initial start-up, reducing nuisance tripping of input circuit breakers. The series is suitable for a wide range of applications, including conventional switch cabinets, decentralized machinery and industrial systems. Other Benefits: • DC-OK and inhibit relay contacts for professional integration into applications control architecture • Parallel mode switch to activate load balancing behavior • Very low inrush energy peak saves cost for input line protection • High efficiency and low stand-by losses contribute to an eco-friendly energy footprint • Designed to meet the most accepted IEC safety standards, and regulatory EMC standards on radiated emission
