The Sorensen DCS20-50 is a 1000 W programmable DC power supply engineered for laboratory, industrial, and OEM applications requiring stable, adjustable output across a wide range of loads. It delivers continuously variable output from 0–20 VDC at 0–50 ADC, with high-frequency switching regulator technology enabling compact form factor and high power density. Line and load regulation of 0.1% (or 0.05% of maximum) ensures stable operation across AC input variations and load transients. Ten-turn potentiometers provide high-resolution voltage and current adjustment with simultaneous digital display. Built-in overvoltage protection, remote sensing (up to 1 V/lead compensation), and transient recovery within 500 µs to 1 ms support demanding test, burn-in, and R&D workflows. Multiple control and programming interfaces, optional IEEE-488/RS-232, and RS-485 multichannel slave capability enable integration into automated test systems.
