Product Overview


Product Description

FD100 Series
The FD100 series frequency converter is a high-performance frequency converter independently developed, designed, and produced by FGI. As the company's future main model, this series of frequency inverters has fully researched market demand, adopted a new structural design, optimized hardware and software configuration, achieved higher performance and precision motor speed control.

We have always adhered to the use of standardized and refined management processes, starting from every detail and continuously improving the stability and reliability of our variable frequency drives (VFD).

This series of AC drives, with their stable and reliable operating performance, is highly trusted by customers and widely used in industries such as textiles, paper making, machine tools, packaging, food, fans, water pumps, and various automated production equipment.
