The TDK-Lambda GEN30-110 is a 3.3 kW programmable DC power supply engineered for OEM, industrial, and laboratory applications demanding precision voltage and current control. This 2U rack-mount instrument delivers 0–30 VDC output at 0–110 A, with typical efficiency of 86% and active power factor correction (0.99 typical single-phase, 0.92–0.94 three-phase). Input configurations span 170–265 VAC single-phase, 170–265 VAC three-phase, and 342–460 VAC three-phase at 47–63 Hz.
