The Agilent/Keysight E3612A is a 30 W benchtop DC power supply delivering single-output voltage regulation across dual ranges: 0–60 Vdc at 0–0.5 A, or 0–120 Vdc at 0–0.25 A. Operating in both constant voltage (CV) and constant current (CC) modes, the unit combines precision output control with exceptionally low noise performance, making it suited for laboratory power sourcing, circuit validation, and component testing where output stability is critical.
