The HP/Agilent 6456B is a 3600 W SCR-regulated DC power supply delivering 0–36 V DC and 0–100 A DC for high-current industrial and laboratory applications. Dual front-panel meters provide real-time voltage and current monitoring across 0–40 V and 0–100 A scales. The unit operates in both constant voltage and constant current modes, with selectable voltage and current limit controls.
