The Sorensen DCS80-37 is a 3 kW programmable DC power supply delivering 0–80 VDC at 0–37 A for demanding research, development, and industrial testing applications. This low-profile unit combines high power density with precise voltage and current control, automatic CV/CC mode crossover, and exceptional line and load regulation (0.1% each). The 2960 W output integrates remote sensing, multiple programming interfaces, and robust thermal management in a compact 33 lb chassis.
