SCR DC MOTOR CONTROLLER

Summary:

DC motor drive adopts SCR chopper, which has unique trigger mode, thus making it more accurate and reliable. The drive is the update speed regulation product which develops and produces in combination with the international standard requirements and absorbs advanced technology experience. The drive has high performance-cost ratio because of its excellent performance and reliable quality. (It can reach high speed ratio even when at non-speed feedback) It is in DC motor drive field. Currently, the serial products have been exported to many countries and widely used in fields of domestic , food machinery, cable equipment, , papermaking, ?printing, , equipment, and so on.
