XHR provides 1000 watts of programmable DC power in a compact half-rack package. It is available in eighteen 1 kW models. Its unique features and size make XHR ideal for OEM applications where high power and wide adjustment of output voltage or current is required, and a compact half-rack configuration is advantageous.

It is stackable with a small foot print, front panel binding post connectors and a low current requirement that allows it to be plugged into a standard 120 VAC, 15 A circuit. State-of-the-art zero voltage or “soft” switching technology virtually eliminates switching transients for high efficiency, low noise and high reliability. XHR is also power-factor-corrected for low current draw (only 11 A at 120 VAC for 1000 watts) and reduced generation of input current harmonics.

The half-rack XHR is ideal as a “companion” for another half-rack instrument in a test system equipment console, eliminating the need for a blank panel while preserving vertical rack space. With a choice of rear and/or front panel connectors, XHR offers added system flexibility.
