Ametek / Xantrex / Sorensen XFR 20-60 Programmable DC Power Supply

The Ametek/Xantrex/Sorensen XFR 20-60 is a 1200-watt programmable DC power supply designed for a variety of applications, including research, product development, and production testing. It offers a stable and adjustable DC voltage and current output, controllable via remote interfaces. The XFR series utilizes “soft switching” technology, which minimizes switching transients, improves efficiency, reduces heat generation, and enhances reliability. These units are engineered for excellent thermal management, allowing them to be stacked in rack mounts without requiring additional ventilation space between them. The power supply operates in both Constant Voltage (CV) and Constant Current (CC) modes, with automatic crossover between them. It features a 19-inch rack-mountable package, occupying only 1U of vertical space, making it suitable for both benchtop and system integration.
