Ametek / Xantrex / Sorensen XFR 7.5-140 Programmable DC Power Supply

The Ametek / Xantrex / Sorensen XFR 7.5-140 is a 1200W programmable DC power supply designed for a variety of testing and research applications. It features “soft switching” technology for high efficiency and low noise, constant voltage/constant current operation, and adjustable overvoltage protection. This unit is built for continuous use and can be rack-mounted, occupying only 1U of vertical space, and can be stacked without requiring ventilation space between units.
