Sorensen XHR Series
1 kW
DC Power Supply
• Universal input 85-250 Vac
• Power Factor Correction (PFC)
• Zero voltage “soft switching”
• Simultaneous front panel display
voltage and current
• Constant voltage or constant current operation
• Front and rear connectors
• Remote sense with 5 V line loss compensation
• LabVIEW® and LabWindows® drivers
The Sorensen XHR Series provides 1000 watts
of DC power in a compact half-rack package.
The supplies are designed for benchtop and
system use, and as an ideal companion for other
half-rack instruments in a test console. Its unique
size also eliminates the need for a blank panel to
preserve vertical rack space for OEM applications.

The XHR is power factor corrected for low current
draw - only 11 amps at 120 volts AC for 1000
watts - and reduced generation of input current
harmonics. Zero voltage or “soft switching”
virtually eliminates switching transients for high
efciency, low noise and high reliability. It is also
stackable, with a small footprint, front panel
binding post connectors, and a low current
requirement with universal input, making the XHR
ideal for benchtop applications.

Specications subject to change without notice.
1. Specications indicate typical performance at 25°C ± 5°C, nominal line input of 120 Vac.
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 efciency at 115 Vac input and rated output power.
8. Apply accuracy specications 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.
