Product Description

AF400M Static Frequency Converter – Short High-Converting Description

What Static Frequency Converter is designed to solve？

Many aviation and test facilities face the same issues:

Standard 50/60Hz power cannot simulate aircraft 400Hz systems
Rotary converters create noise, vibration, and high maintenance cost
Voltage fluctuation leads to unstable test results
High harmonic distortion affects sensitive avionics equipment
Limited flexibility for single-phase and three-phase testing setups

These problems directly impact testing accuracy, efficiency, and operational safety.

The AF400M provides a stable and controlled 400Hz aircraft power simulation system, ensuring:

Accurate conversion from 50/60Hz to 400Hz
Clean sine wave output for avionics and aerospace systems
Stable voltage regulation within ±1%
Safe isolation between input and output systems
Reliable operation under continuous industrial load

It replaces traditional rotary frequency converters with a more stable and low-maintenance solid-state solution.

Compared with most market alternatives, AF400M offers a more balanced industrial solution: More stable than rotary frequency converters (no mechanical wear) Lower harmonic distortion than many low-cost static converters Wider power range suitable for aviation + industrial testing Better long-term reliability for continuous operation Easier maintenance and lower lifecycle cost While some European and US brands focus on high-end laboratory systems, AF400M is designed for practical aviation ground use with industrial durability and cost efficiency.

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.
