The Xantrex XHR20-50 is a 1000 W programmable DC power supply engineered for benchtop and system integration applications. It delivers 0–20 Vdc and 0–50 Adc in constant voltage or constant current modes, with universal input acceptance (85–250 Vac). Zero voltage soft switching and integrated power factor correction minimize input current harmonics while maximizing efficiency. The half-rack form factor occupies less than 3.5 inches of vertical space, making it ideal for OEM integration and test console deployment without sacrificing rack real estate.
