Agilent/Keysight AC6804B

The Keysight AC6804B is a 4 kVA AC/DC power source engineered for comprehensive testing of electronic equipment across variable power conditions. It delivers stable AC output to 310 Vrms at 20 A, or DC output to 438 V at 16 A, with programmable control over voltage, frequency, and current. The instrument operates from standard single-phase mains (100–240 Vrms, 50/60 Hz) and accommodates load power factors from 0 to 1 in either leading or lagging configuration.

Front-panel operation and remote control via LAN/LXI, USB, or optional GPIB interfaces enable flexible test automation and monitoring.
