VARIABLE FREQUENCY DRIVE (VFD)

The VFD Panel (Variable Frequency drive panel) also known as VFD Control Panel are designed to control the speed of the electric motor and feed pump. They are widely used in drilling, pumping and other large machine applications like Conveyor and Compressor.

The most common uses of a VFD are for control of fans, pumps and compressors, and these applications account for 75% of all drives operating globally. Soft starters and across-the-line contactors are other, less sophisticated types of motor controllers.

A VFD control panel typically houses a selection of control panel components including a VFD, harmonic filters, line reactors, surge protectors, a bypass, circuit breakers, motor starters, soft starters and some kind of cooling unit, as VFD's tend to produce a lot of heat.
