The Sorensen DCS150-7 is a 1 kW programmable DC power supply engineered for laboratory testing, component evaluation, and automated test equipment systems. It delivers 0–150 V DC at 0–7 A with precise voltage and current control via 10-turn potentiometers. The unit operates in constant voltage and constant current modes with automatic crossover, incorporates high-frequency switching technology for compact power density, and includes standard adjustable crowbar-type over-voltage protection.
