40A DC Motor Speed Controller PWM

The PWM DC motor speed controller 40A 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.

PWM DC Motor Speed Controller, DC 10-55V/40A, LED Display DC Motor Speed Controller with Adjustable Potentiometer and Forward-Brake-Reverse Switch

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

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.

The unit has FF/Rev switch to run the motor both ways and display the % of the PWM duty.
