The Sorensen DCR40-60A is a 0–40 Vdc, 0–60 Adc adjustable power supply engineered for laboratory testing, component evaluation, and industrial control applications requiring stable voltage and current regulation. Built on SCR preregulator topology, it delivers constant voltage regulation of ±0.075% or ±15 mV and constant current regulation of ±60 mA, with transient recovery within 50 ms following a 50% load change.
