The FVC Series frequency converters provide a robust and cost-effective solution for delivering AC power from 5kVA to 1000kVA, with adjustable output voltage and frequency to support a wide range of testing and validation applications.
Designed with low-distortion output and three-phase architecture, the FVC Series offers single or dual voltage range configurations and overload capability, making it well suited for testing avionics equipment, transformers, motors, pumps, and other frequency-sensitive systems.
The system supports frequency conversion from 50Hz or 60Hz input to programmable output frequencies while maintaining stable and regulated AC power. These capabilities make the FVC Series an ideal solution for limit and immunity testing of AC-powered equipment.

A frequency converter changes the input frequency and voltage to simulate non-standard power conditions, widely used for testing avionics, motors, and export-compliant equipment.
Advanced frequency converters typically support wide ranges such as 15 Hz to 450 Hz, enabling testing of aerospace, defense, and specialized industrial equipment.
Fast recovery time (e.g., 2 ms) ensures stable output during sudden load changes, which is critical for accurate and repeatable testing.
Yes, frequency converters are widely used for avionics, defense, and aerospace testing where non-standard frequencies like 400 Hz are required
Key factors include power rating, frequency range, voltage stability, accuracy, response time, and compatibility with the test application.
