The Sorensen SGA160-31C-1AAA is a programmable DC power supply from the SG Series, delivering 160 V at 31 A (5 kW maximum power) with CV/CC automatic crossover operation. Built for test, measurement, R&D, and automated systems, this unit combines precise analog control with exceptional load transient response—recovering within 1 ms to ±0.75% of steady-state output during 50–100% load steps. The SGA features front-panel 10-turn potentiometers, 3.5-digit LED readout, and remote analog programming and read-back capability.
