Sorensen DHP30-220

The Sorensen DHP30-220 is a programmable DC power supply delivering 6600 W across a 0–30 VDC output range at up to 220 A. Built for precision test, R&D, and manufacturing environments, it operates in Constant Voltage, Constant Current, and Constant Power modes with output ripple and noise held to 10 mV maximum. Line and load regulation maintain 0.1% voltage and 0.5% current stability relative to maximum rated output. The unit responds to transient load changes within 2 ms and holds ±0.05% stability over 8-hour intervals after 30-minute warm-up.
