The Sorensen DCR150 is a 0–150 VDC power supply designed for industrial, laboratory, and test environments requiring stable voltage and current delivery. The unit automatically crossovers between constant voltage (CV) and constant current (CC) modes, eliminating manual switching and enabling operation across diverse load conditions. Adjustable current limiting with automatic recovery protects against overload and short-circuit faults, while no overshoot occurs at turn-on, turn-off, or power failure.
