Agilent/Keysight 6299A DC Power Supply

The Agilent/Keysight 6299A is a benchtop DC power supply delivering 0–100V at 0–0.75A (75W total) with automatic constant voltage/constant current crossover. Though manufacturer-obsolete, it remains viable for low-power circuit characterization, sensor testing, and integrated circuit validation requiring stable, regulated output.
