Product Description

VFD

This series of frequency converters is a general-purpose high-performance current vector frequency converter, mainly used to control and regulate the speed of three-phase AC asynchronous motors. Adopting high-performance vector control technology, with low speed and high torque output, it has good dynamic characteristics, strong overload capacity, added user programmable function and background monitoring software, communication bus function, support for multiple PG cards, etc., with rich and powerful combination functions and stable performance. It can be used as a driver for textile, papermaking, wire drawing, machine tools, packaging, food, fans, water pumps, and various automated production equipment.
