The HP/Agilent 6479C is a high-power SCR-regulated DC power supply delivering 0–300 V at 35 A (10.5 kW) for demanding test and industrial applications. This unit operates in both constant voltage and constant current modes, with precise regulation across line and load variations. Large front-panel meters provide real-time voltage and current monitoring. Remote sensing and programming capabilities enable system integration, while master/slave configurations support series, parallel, and tracking operation for expanded output capability.
