The TDK-Lambda Genesys™ GEN 125-120 is a 15 kW programmable DC power supply delivering 0–125 Vdc at 0–120 A output. This 3U rackmount unit combines constant voltage/constant current (CVCC) auto-crossover operation with active power factor correction (0.99 typical) and low output noise for demanding test, industrial, and OEM applications. Voltage ripple noise measures 0.025 Vrms; current ripple noise 0.05 Arms (5 Hz to 1 MHz bandwidth). The supply accepts three-phase AC input at 47–63 Hz; the 3P208 variant operates from 180–253 Vac while the 3P480 variant accepts 432–528 Vac. Efficiency reaches 88% typical.
