The Xantrex XKW300-3.5 is a programmable DC power supply delivering 3000 W of stable, variable output in a compact 19-inch rack form factor. Built on high-frequency PWM switching technology operating at 30 kHz nominal, it serves research, product development, production testing, ATE, process control, electroplating, and burn-in applications. The unit supports both single-phase (200–250 VAC at 26 Arms) and three-phase (190–250 VAC at 16 Arms) input with selectable 115/230 VAC operation.
