The Xantrex XFR 1.2 kW programmable DC power supply provides clean, reliable power for research, product development, production test applications, and OEM applications where high power and a wide adjustment of output voltage or current are required in a 19-inch rack package. The XFR 1.2 kW is packaged in a 1.75-inch (1 U) high chassis and offers twenty percent more power than any competitive product in a similar package. The supplies have excellent thermal management allowing for units to be stacked in rack mounts without any ventilation space required between each unit. They also offer high reliability with zero voltage, or “soft switching”, which virtually eliminates switching transients for high efficiency, decreased heat generation, and reduced stress on the switching transistors. 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
