The Xantrex XKW60-50-M9A is a programmable 3000 W DC power supply for research, development, and production test environments demanding high power density in a compact footprint. Operating from single-phase (180-264 VAC) or three-phase (190-250 VAC) mains at 47-63 Hz, this 2U rackmount unit delivers 0-60 V and 0-50 A with constant voltage/constant current modes and automatic crossover. Efficiency exceeds 90%, while low ripple and noise at 60 kHz ripple frequency ensures clean output suitable for sensitive device characterization and stress testing.
