Product Description

AF400M Static Frequency Converter – Short High-Converting Description

What Static Frequency Converter is designed to solve？

In practice, customers usually face these issues:

Aircraft systems require 400Hz power, but site power is 50/60Hz
Test results are unstable due to waveform distortion
Rotary converters are noisy and require frequent maintenance
Sensitive avionics react to voltage fluctuation
Lab setups need both single-phase and three-phase flexibility

ACSOON AF400M is an industrial-grade 400Hz static frequency converter designed for aircraft ground power, aerospace testing, and aviation maintenance applications. It converts standard 50Hz/60Hz utility power into stable 400Hz pure sine wave output with low harmonic distortion and high voltage stability, ensuring reliable performance for sensitive avionics and test equipment.

Built with IGBT technology and isolated transformer design, AF400M delivers clean, regulated AC power with full protection and real-time monitoring, making it a dependable solution for MRO facilities, airports, and aerospace laboratories worldwide.
