The motor speed controller can easily provide a continuous current of3A to your DC motor or other DC load. Connect your DC motor (or DC load) to the motor terminals as indicated on the wiring diagram. Connect a voltage of 10V-36V DC to the circuit making sure of the correct polarity of the connection. Note that the voltage applied to the motor will be supply voltage applied to the circuit. It is recommended to add an appropriately rated fuse inline with the positive supply in order to protect the circuit from any possible short circuits. You can now control the speed of the motor through potentiometer.
