XFR 1.2 kW XFR 1.2 kW Programmable DC Power Supply with Zero Voltage “Soft Switching” Provides 1.2 kW of DC Power for OEM Applications Xantrex Technology Inc. Headquarters The Xantrex XFR 1.2 kW programmable DC power supply provides clean, reliable power for research, 8999 Nelson Way product development, production test applications, and OEM applications where high power and a Burnaby, British Columbia wide adjustment of output voltage or current are required in a 19-inch rack package. The XFR 1.2 kW is Canada V5A 4B5 packaged in a 1.75-inch (1 U) high chassis and offers twenty percent more power than any competitive 800 670 0707 Toll Free product in a similar package. 604 420 1591 Fax The supplies have excellent thermal management allowing for units to be stacked in rack mounts 5916 195th Street NE without any ventilation space required between each unit. They also offer high reliability with Arlington, Washington zero voltage, or “soft switching”, which virtually eliminates switching transients for high efficiency, USA 98223 decreased heat generation, and reduced stress on the switching transistors. 800 446 6180 Toll Free 360 925 5144 Fax Product Features Zero voltage “Soft Switching” Simultaneous front panel display of output voltage and current Constant voltage or constant current operation Remote sense with 5 V line loss compensation LabVIEW® and LabWindows® drivers Protection Features Over voltage protection Over temperature protection Options Isolated analog control (ISOL) RS-232 interface card GPIB interface card GPIB-multichannel © 2004 Xantrex Technology Inc.
