The Sorensen DCR60-30B is a 1800 W DC power supply delivering 0–60 Vdc at 0–30 A for laboratory, industrial, and burn-in testing applications. Built around SCR or Triac phase control followed by passive LC filtering, this unit maintains tight regulation across its operating envelope while supporting both constant voltage and constant current modes with automatic crossover.
