A frequency converter – or variable frequency drive (VFD) – is an electric device that converts a current with one frequency to a current with another frequency. The voltage is normally the same before and after frequency conversion. Frequency converters are normally used for speed regulation of motors used to drive pumps and fans.

A Dual-Power Dual-VFD (Variable Frequency Drive) Fan System is an advanced industrial ventilation solution designed for high reliability, energy efficiency, and uninterrupted operation in critical environments such as mines，tunnels and so on.

A High Voltage Variable Frequency Drive (HV VFD) is a power control device designed to adjust the speed and torque of high-voltage motors (typically rated at 3kV, 6kV, 10kV, or higher) by varying the input power frequency, enabling energy savings, soft starts, and precise motor control.

Low voltage mining explosion-proof frequency converter is a power control equipment designed specifically for flammable and explosive environments such as coal mines and metal mines, used to drive mining machinery such as fans, water pumps, belt conveyors, and elevators. Its core features are explosion-proof safety design and adaptability to harsh working conditions, while also possessing functions such as high efficiency, energy saving, and intelligent control.

Application: this product is applied to soft starting, soft stopping, operation process control and energy-saving application of motor in harsh environment such as coal mine, other mines, petroleum and chemical industry.
