Agilent/Keysight AC6906H

The Keysight AC6906H is a 6 kVA three-phase AC power source engineered for rigorous testing of electronic devices across R&D, manufacturing, and quality control environments. It delivers stable, accurate AC power with output voltage up to 320 Vrms (AC) and 452 V (DC), operating at frequencies from 1 Hz to 5 kHz. The instrument combines power sourcing with integrated measurement - multimeter, harmonic analyzer, and power analyzer functions - enabling both stimulus and verification in a single platform.
