Keysight AC6918H/200 AC Power Source

Overview

The Keysight AC6918H/200 is an 18 kVA three-phase AC power source from the AC6900 Series, engineered for comprehensive AC and DC power testing with high-frequency capability. It integrates multimeter, harmonic analyzer, and power analyzer functions into a single precision instrument. With 18 kVA capacity and frequency capability up to 5 kHz, it is designed for high-frequency avionics and aerospace equipment testing in compliance with RTCA DO-160 and MIL-STD-704 standards.
