The Sorensen SRL60-35 is a 2000 W DC power supply delivering 0–60 VDC at 0–35 ADC for laboratory, industrial, and educational applications. It operates in constant voltage and constant current modes with automatic crossover, achieving 0.01% or 2 mV line and load regulation in voltage mode and 0.2% + 4 mA in current mode. Output ripple is 200–700 µV rms in voltage mode and 0.5–10 mA rms in current mode, with transient response of 150 µs typical for 100% load changes. The unit accepts 190–230 VAC input at 47–63 Hz without derating and employs SCR preregulation with a linear series pass design for high efficiency.
