The Sorensen DCR32-155T is a 5 kW programmable DC power supply engineered for high-demand burn-in testing, manufacturing, and research applications. It delivers 0–32 VDC at 0–155 ADC with exceptional output regulation, low ripple, and automatic voltage/current crossover. The supply operates from 208 VAC ±10%, 3-phase, 60 Hz input (alternative input voltages available) and incorporates comprehensive remote control via analog programming and IEEE-488 interface. Forced-air cooling and a compact Case II form factor (8¾” high) suit both bench and rack integration.
