1.0INTRODUCTION



MD30C is the successor of MD30B which is designed to drive medium to high power              

brushed DC motor with current capacity up to 80A peak and 30A continuously. Fully NMOS              

design not only provides faster switching time, it is also more efficient and no heatsink or fan                

isrequired.



Besides that, MD30C also incorporates some user friendly features such as reverse polarity            

protection and onboard PWM generator which allows it to operate without a host controller.             

The motor can simply be controlled with the onboard switches and speed potentiometer.            

Externalswitchesandpotentiometercanalsobeused. 
