PWM DC motor speed controller 3A.
The PWM DC motor speed controller 3A 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 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.

Surprised at the great service. Good communication. Speedy delivery. Have tested the product and it actually exceeds expectations.
I use these as a dimmer for 12v LED strip, works with no visible flicker. The rotary potentiometer also has an off position.
