Keysight AC6906H/400 Three-Phase AC Power Source

Overview

The Keysight AC6906H/400 is a three-phase AC power source from the AC6900 Series designed for testing avionics equipment and high-frequency power systems. It delivers 6 kVA of power with output voltages up to 320 Vrms and frequency capability up to 5 kHz. The unit operates in AC, DC, or combined AC plus DC modes, making it versatile for various testing scenarios including pre-compliance testing per RTCA DO-160 and MIL-STD-704 standards.
