The Sorensen DHP30-330 is a high-power DC supply delivering 0–30V and 0–330A for demanding industrial test, simulation, and development environments. This 10 kW unit operates in constant voltage, constant current, and constant power modes with exceptional line and load regulation of 0.1% (voltage) and 0.5% (current). Voltage ripple measures 10–15 mV RMS, while transient response recovers within 2% in 10 ms following a 30% load step. Temperature stability is maintained at 0.02%/°C (voltage) and 0.03%/°C (current).
