Sorensen (Xantrex) XFR Programmable Analog DC Power Supplies

Sorensen (Xantrex) XFR Programmable Analog DC Power Supplies


Product Overview

XFR is the smart choice for research, product development and production test applications such as R&D, magnet control, product design, ATE, process control, electroplating and burn-in. The unique features of XFR make it the best choice for applications where high power and a wide adjustment of output voltage or current are required in a full 19-inch rack package. Choose from ten 2800-watt models.

Zero voltage, or “soft” switching, provides significant benefits. Switching transients are virtually eliminated and noise performance is closer to linear levels. Efficiency is increased, heat generation is decreased, and stress on the switching transistors is reduced – improving reliability (MTBF). Unlike most competitive products, XFR generates full power at full rated current over its total operating range of 0 to 50° C without derating. XFR is also designed with excellent thermal management, so units can be stacked in rack mounts without leaving ventilation space between each unit.
