PWM DC motor speed controller 20A.

The PWM DC motor speed controller 20A is very easy to use, simply connect your power wires to the power terminals marker power + and power -. Then connect the motor to the terminals marked motor + and motor - and you are done.

This module uses PWM modulation instead of simply changing the voltage which is much more efficient but also will not burn your motors accidentally.

With the PWM modulation, you get less heat dissipation over your switching device than over a linear voltage adjustment regulation. With less heat, it will run cooler on high currents while giving enough torque to your motor.
