The Xantrex XFR20 series is a line of programmable DC power supplies engineered for research, development, production testing, and OEM integration. These 1U rack-mount units leverage zero voltage soft switching technology to minimize switching transients, delivering high efficiency, reduced heat generation, and low output noise. Available in 1200 W and 2800 W configurations, the XFR20 excels in space-constrained environments—units stack without requiring ventilation space between them, a critical advantage for system integrators and labs managing confined rack installations.
