Atec XHR User Manual
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.
