The Xantrex XHR33-33 is a programmable DC power supply delivering 0–33 V at 0–33 A with 1000 W maximum output. Built for precision voltage and current control in research, development, production testing, and educational environments, it combines zero voltage soft-switching technology with power factor correction (0.99 minimum) for high efficiency and low harmonic distortion. The unit accepts universal AC input from 85–250 VAC and operates in constant voltage or constant current modes with automatic crossover.
