The HP/Agilent 6299A is a single-output DC power supply delivering 0–100V at 0–0.75A (75W maximum). Designed for precision laboratory and industrial applications, it operates in both constant voltage and constant current modes with exceptional load and line regulation. The 10-turn voltage control enables fine adjustment across the full range, while front-panel metering (selectable X1 and X0.1 ranges) displays voltage or current in real time.
