Company Introduction


 Our company is a manufacturer of professional frequency inverters integrating research and development, production and sales. With advanced technologies, excellent quality, scientific management and perfect services, we are building a first-class inverter manufacturer gradually.

Our company has independently developed a series of technologically advanced and fully functional high-end inverters. Currently, our company has introduced CHINSC inverter models such as SVF3000 series, SVF-M series, SVF-EV series, SVF-G7 Series 0.4 ~ 630KW, to the markets. With excellent product quality, excellent technology development capabilities and comprehensive after-sales services, CHINSC inverters have won praise among agents and customers across the country. 

We are dedicatedly engaged in supplying a unique range of A.C Drive to the customers. They are used in various applications that includes paper making, crane, elevator, manipulator, air-compressor and in various other sectors. These drives are easy to install and are manufactured by using best quality raw material. Our team has thoroughly checked these drives on the various parameters before delivery.
