DC motor driver
220DR20AL Product introduction
Mmt-220dr series DC motor driver is a speed regulating product developed and produced on the basis of absorbing previous successful experience and combining with modern advanced technology. This series of products have reached the standard requirements and are exported to many countries. The driver adopts SCR chopping principle and unique triggering mode, and can achieve high speed ratio without speed feedback, so its control is more accurate and reliable. Products with excellent performance, reliable quality and high cost performance are widely used in plastic machinery, food machinery, cable equipment, mechanical processing, paper printing, test equipment, laboratory equipment, mixing equipment and other fields.
