The Sorensen DCS20-150 is a programmable DC power supply delivering 3 kW of continuous output power across 0–20 VDC and 0–150 A. Built on high-frequency switching architecture, it achieves exceptional power density in a compact 19-inch chassis while maintaining voltage ripple at 0.2% RMS and load/line regulation of 0.1%. The unit operates in constant voltage or constant current mode with automatic crossover, supported by adjustable over-voltage protection, overcurrent protection, and overtemperature shutdown.
