The Sorensen XPF60-20 is a 420W single-output programmable DC power supply engineered for precision voltage and current control in demanding test and industrial applications. Built on PowerFlex architecture, it combines high-frequency switch-mode pre-regulation with a linear post-regulator to deliver low noise performance and fast transient response across a flexible operating envelope. The unit supports dynamic voltage and current combinations up to 60V/20A, automatically transitioning between constant voltage and constant current modes. Housed in a compact ¼ rack width, 3U chassis, it integrates analog controls with digital functionality including S-Lock settings protection for bench and rack-mount deployment.
