The Sorensen DHP60-220 is a programmable DC power supply delivering 0–60 V and 0–220 A for demanding test, systems, and industrial applications. It operates in constant voltage, constant current, and constant power modes with line and load regulation of 0.1% (voltage) and 0.5% (current). Programming resolution and accuracy meet 0.3% and 0.10%+0.3% specifications respectively. The unit recovers from a 30% load step to within 2% in 10 ms, with output ripple and noise at 15 mV RMS.
