The TDK-Lambda GEN500-20 is a 10 kW programmable DC power supply delivering 500 Vdc at 20 A output. Built for industrial, medical, and ATE applications, it combines high efficiency (83% typical) with precise regulation and multi-interface control. The unit operates from three-phase 180–253 Vac input and features voltage ripple of just 0.06 Vrms and current ripple of 0.008 Arms across the 5 Hz to 1 MHz bandwidth. Engineered for demanding test and manufacturing environments, it provides flexible programming via analog inputs, resistor networks, or serial communication.
