The Sorensen DCR80-6B is a 450 W DC power supply engineered for benchtop and system integration test environments. It delivers 0–80 VDC at 0–6 A with automatic constant voltage (CV) and constant current (CC) mode crossover, panel-indicated operation. Line and load regulation in voltage mode is 0.05% of E or 10 mV maximum; current mode stability holds 0.15% of I maximum after 30-minute warm-up. Voltage ripple measures 3.3 mV RMS, with transient response of 1.8 ms for 50% load changes and zero overshoot at turn-on, turn-off, or power failure.
