The Sorensen DHP50-40 is a programmable DC power supply delivering 2.0 kW across 0–50 VDC and 0–40 A in a single-output configuration. Designed for research, development, and test environments, this unit operates in Constant Voltage, Constant Current, and Constant Power modes with ±0.1% voltage regulation and ±0.2% current regulation. Output stability reaches ±0.05% after 8 hours warm-up, with transient response of 2 ms to steady state for 30% load steps. The DHP50-40 accepts 190–253 VAC, 47–63 Hz single or three-phase input and achieves minimum 80% efficiency at full load.
