SKU: DGM PWM DC MOTOR CONTR 3A BI-DIR
DC Motor Speed Controller allows controlling both the speed and direction of a DC motor using a Pulse-Width-Modulated (PWM) DC voltage with a Duty Cycle fully adjustable from 10%-100% (both Positive and Negative DC output). The motor speed controller incorporates a high power MOSFET with a heat sink and can easily provide a continuous current of 3A to your DC motor or other DC load. The circuit also includes LED whose brightness varies proportional to the relative speed of the motor therefore giving a visual feedback of the current speed.
Important Notes :
An appropriately rated fuse (rated a little higher than the maximum current you expect to draw) is recommended to ensure safe operation. The controller is NOT reverse-polarity protected and will be damaged if connect the supply voltage with wrong polarity. Double check all connections before applying power and always turn off the power supply before making any wiring changes.
