Agilent/Keysight AC6912L

The Keysight AC6912L is a 12 kVA three-phase AC power source that merges power generation with integrated multimeter, harmonic analyzer, and power analyzer functionality. Designed for rigorous electrical system testing, it outputs up to 320 Vrms AC (452 V DC maximum) across configurable single-phase, single-phase three-wire, or three-phase four-wire topologies. The instrument operates from 1 Hz to 550 Hz, supporting AC, DC, and AC+DC modes simultaneously.

It generates custom waveforms, simulates power line disturbances, and measures voltage, current, and power with ±(0.15% + 0.3 V) accuracy across the 45 Hz to 500 Hz band. Built-in harmonic analysis, output sequencing, and programmable soft start/stop and output inhibit functions enable compliance testing for avionics (RTCA DO-160, MIL-STD-704) and general component validation including relays and transformers.
