Frequently Asked Questions

What is a frequency converter?

A frequency converter changes the input voltage and frequency (e.g., 110V 60Hz) to a different output (e.g., 220V 50Hz) with a pure sine wave, allowing equipment to operate on foreign power grids.

How is it different from a VFD?

VFDs (Variable Frequency Drives) are designed only for motor speed control. Our frequency converters work with any electrical device — computers, medical machines, test equipment — not just motors.

Can I convert 50Hz to 60Hz?

Yes. Our converters support bidirectional conversion between 50Hz and 60Hz, as well as to 400Hz for aviation and military applications.

Do you offer custom solutions?

Yes. We provide customized frequency converters and AC power sources tailored to specific voltage, frequency, and power requirements.
