The Sorensen SGA80X185C is a programmable analog DC power supply delivering up to 80V and 185A (14.8 kW) for demanding laboratory and systems test applications. Part of the SGA Series, this unit combines exceptional load transient response, low noise output, and high power density in a compact form factor. Constant voltage/constant current operation with automatic crossover accommodates diverse load conditions. Front-panel potentiometers and 3½ digit LED readout enable intuitive manual control, while standard non-isolated remote analog control supports external command integration. The supply operates from 3-phase, 3-wire plus ground AC input (47–63 Hz nominal) and delivers exceptional regulation and stability across load and line variations.
