The Sorensen DHP50-60 is a programmable DC power supply delivering 3000 W of output power in a single chassis. It operates across 0–50 VDC at 0–60 A, supporting constant voltage, constant current, and constant power modes for laboratory, R&D, and manufacturing test environments. The unit combines low output ripple (10 mV typical), fast transient response (2 ms to steady state for 30% load step), and tight line and load regulation (0.1% voltage, 0.5% current) to meet precision power delivery requirements. Multi-step sequencing capabilities—up to 9 steps per sequence, 99,999 seconds per step—enable complex automated test protocols. Voltage, current, and duration are independently programmable. The front panel keypad provides direct control with nine nonvolatile memory slots, while soft calibration adjusts output without chassis disassembly. Remote sense terminals compensate for line drop up to 3% of rated voltage. Temperature stability is ±0.05% after 8-hour warm-up, with temperature coefficients of 0.02%/°C (voltage) and 0.03%/°C (current). Input is 200–240 VAC, 3-phase with 0.72 minimum power factor.
