The Sorensen DCS40-25E is a 1.0 kW programmable DC power supply engineered for precision voltage and current control in demanding test environments. Delivering 0-40 Vdc at 0-25 A with high power density in a low-profile chassis, it integrates into ATE systems and rack-mounted configurations. The unit operates in constant voltage and constant current modes with automatic crossover, offering ten-turn potentiometer control with simultaneous digital display. Equipped with adjustable crowbar overvoltage protection (5-110% of rated output), over-temperature protection with LED indication, and remote sensing capability with 4 V maximum sense line drop, the DCS40-25E delivers robust performance across research, development, manufacturing test, and burn-in applications.
