VFD stands for Variable Frequency Drive. These panels are mainly used to control the speed of the electric motors and also of the feed pumps that are used in various industrial facilities. Every motor has varying frequency and voltage; hence they need a separate control panel that will effectively monitor and control them. A VFD control panel brings together or combines motor control devices and circuit protection devices in an enclosure. This control panel also offers protection to these devices from moisture, corrosion, dust, and other damaging factors. VFD control panels have different ratings from NEMA. Some of the most familiar NEMA ratings are NEMA 1, NEMA 3R, NEMA 4, and NEMA 4X. What components does a VFD control panel consist of? A VFD control panel is home to different control panel components like a VFD, line reactors, circuit breakers, harmonic filters, a cooling unit, some motor starters, and a bypass. Why does a VFD need a cooling unit? These control panels tend to produce a lot of heat; hence they require an integration of a cooling unit too. The above-mentioned components are just a few, though a lot more components are present in a VFD control panel. These control panels are frequently used in drilling, pumping, and applications involving heavy-duty, large-scale machineries like Conveyor and Compressor. VFD control panels are available in a variety of power ratings too.
