The Sorensen DCR150-12B is a 1800 W DC power supply delivering stable, adjustable power from 0–150 Vdc at 0–12 ADC. Built on SCR-controlled regulation, it combines precise voltage and current control with automatic mode crossover, current limiting, and optional overvoltage protection. The unit operates from 115 VAC single-phase input (103–127 VAC nominal, 50/60 Hz) with optional 208, 220, or 230 VAC configurations, making it suitable for laboratory testing, component burn-in, and automated test equipment requiring tight regulation and low ripple.
