Sorensen XHR Series (1000W)
Programmable DC power supply in a half rack size, ideal for applications where high power and wide adjustment of output voltage or current is required, and a compact half-rack configuration is advantageous.
Product Overview
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.

1. Specifications indicate typical performance at 25°C ± 5°C, nominal line input of 120 Vac.
3. For 0-100% load variation, with constant nominal line voltage. Measured at the rear panel output connector unless stated otherwise.
4. Maximum drift over 8 hours with constant line, load, and temperature, after 30-minute warm-up.
5. Change in output per °C change in ambient temperature, with constant line and load.
6. Line drop is subtracted from total voltage available at supply output.
7. Typical efficiency at 115 Vac input and rated output power.
8. Apply accuracy specifications according to the following voltage program accuracy example: Set a model 20-50 power supply to 10 V. The expected result will be within the range of 10 V ± 75 mV ± 0.12% of the set voltage
of 10 V. |
