A frequency inverter or an AC drive is more commonly known as a variable frequency drive or simply VFD. It is a piece of electrical power control equipment designed based on inverter technology and microelectronic technology. The frequency inverter is designed to control an AC motor by controlling the motor's power frequency.
Our frequency inverter or AC drive is mainly composed of a rectifier, filter, inverter, braking unit, drive unit, detection unit and micro-processing unit. It provides water pump, elevator and other machinery with variety of protection functions, such as overcurrent protection, overvoltage protection and overload protection, etc.
As a specialized frequency inverter manufacturer and supplier in China, STEP provides a vast range of products, including energy regenerator, high voltage inverter, elevator inverter, full serial VVVF control cabinet, and more.
