The Sorensen DCR150-2.5A is a 400 W DC power supply engineered for precision electronic testing, research, and industrial applications. This unit employs SCR phase control technology to deliver stable, regulated DC power in a compact form factor. It operates across 50–63 Hz input frequencies (without derating at 50/60 Hz) from a 105–125 Vac source and supports both constant voltage and constant current modes with automatic crossover. The supply is well suited for controlled battery charging and discharging, precision electroplating, magnetic device control, and semiconductor life testing.
