The Sorensen DCR600-3B2 is a programmable DC power supply delivering 0–600 Vdc at 0–3 A (1800 W maximum) for precision voltage and current control in demanding applications. Built on SCR preregulator topology with passive LC filtering, this unit operates in constant voltage (CV) or constant current (CC) modes with automatic crossover. It provides exceptional output regulation: CV line and load regulation of 0.05% of E or 75 mV maximum, with 0.1% stability over 8 hours. CC regulation delivers 0.25% line and load performance and 0.15% stability. Output ripple stays minimal at 1200 mV rms in CV mode and 6 mA rms in CC mode. The unit recovers to ±1% of setpoint within 50 ms during 50–100% load transients. Adjustable current limiting with automatic recovery and standard overvoltage protection ensure safe operation across variable loads.
