The Keysight E36312A is an 80 W triple-output DC power supply engineered for benchtop electronic testing, circuit development, and device characterization. It delivers three independent, electrically isolated outputs with precise voltage and current control via dedicated front-panel knobs and a 4.3-inch color LCD display. Output 1 provides 0–6 V at 0–5 A, while Outputs 2 and 3 each deliver 0–25 V at 0–1 A, with series/parallel connection capability to extend voltage or current capacity. The instrument maintains exceptionally low ripple and noise—less than 350 µVrms / 2 mVpp—ensuring signal integrity for sensitive analog and mixed-signal circuits.
