Ametek / Elgar / Sorensen DCS20-50E 1 kW Power Supply

The Ametek/Elgar/Sorensen DCS20-50E is a 1 kW programmable DC power supply for manufacturing test, component evaluation, burn-in, laboratory R&D, and process control. Built on high-frequency switching topology, it delivers stable DC power with adjustable voltage and current settings in a compact 1U chassis. Front-panel ten-turn potentiometers provide high-resolution control with simultaneous digital readout of output parameters.
