The Sorensen QRD40 is a programmable DC power supply engineered for laboratory, industrial, and system integration. Built on a linear pass design, it delivers stable, low-noise output across both constant voltage and constant current operating modes. The unit features standard and high-speed programming capability with remote control options, automatic recovery on transient events, and zero overshoot during turn-on, turn-off, or power failure conditions.
