Ametek / Xantrex / Sorensen XFR 100-28 DC Power Supply

The Ametek / Xantrex / Sorensen XFR 100-28 is a 2800W programmable DC power supply designed for demanding applications in research, development, and production testing. It offers a wide output voltage range of 0-100V and a current capacity of 0-28A. This unit utilizes zero voltage “soft switching” technology to minimize switching transients, resulting in lower noise performance, increased efficiency, and reduced thermal generation, which enhances reliability. The XFR 100-28 is suitable for applications such as magnet control, ATE systems, process control, electroplating, and component burn-in. Its design allows for convenient stacking in standard 19-inch rack mounts without requiring additional ventilation space between units, occupying only 3.5 inches (2U) of vertical rack space.
