The TDK-Lambda GEN 60-55 is a 3.3 kW programmable DC power supply delivering 0–60 Vdc at 0–55 A output. Built for industrial, telecom, and test & measurement environments, it combines precise voltage and current regulation with active power factor correction and multiple communication interfaces. The unit operates from three-phase AC inputs (170–265 Vac or 342–460 Vac, 47–63 Hz) with optional single-phase capability, achieving 88% typical efficiency and 0.99 power factor at full load. Voltage ripple noise measures 0.008 Vrms and current ripple 0.1 Arms across the 5 Hz to 1 MHz bandwidth. Housed in a compact 2U rack-mount or bench-top enclosure (423 × 88 × 442.5 mm, 13 kg), the supply includes 16-bit ADC/DAC converters for high-resolution programming and automatic CV/CC mode crossover.
