Keysight AC6903L Three-Phase AC Power Source

Overview

The Keysight AC6903L is a three-phase AC power source from the AC6900 Series, offering 3 kVA power capacity with rms voltages up to 320 V. The instrument operates in AC, DC, or AC plus DC mode for versatile testing scenarios. It features frequency capability up to 550 Hz, built-in tests for power line disturbance and output sequencing, harmonic analysis capabilities, and waveform generation. The AC6903L is particularly suited for avionics equipment testing and pre-compliance validation.
