Overview
The Medium Voltage Variable Frequency Drive (VFD) Cabinet is a high-performance motor control solution designed for 3kV to 11kV motors, typically used in applications such as fans, pumps, compressors, and other heavy-duty equipment. It enables soft start and variable speed control, improving energy efficiency, reducing mechanical stress, and minimizing grid impact during motor start-up.
This system integrates a medium voltage inverter, isolation transformer, protection module, cooling system, and a user-friendly HMI interface within a compact, modular enclosure. It features comprehensive protections including overvoltage, overcurrent, overheating, phase loss, and ground fault detection.
