Control the speed of a DC motor with this controller, with reverse polarity protection, high current protection, high conversion efficiency, stable circuit and performance.

PWM Motor Speed Controller: High efficiency, high torque, low heat generating. Adopt PWM speed regulation technology, it can easily provide a continuous current.

Attached a potentionmeter for regulating the speed and attached a reversible switch for controlling the forward, reverse direction or stopping DC motor controller.

Wide Speed Regulating Range: DC 10V-30V; Maximum output power is 120W; Max Current: 4A.

Maximum Continuous Output Current: 3A ; Overload short circuit protection current: 4A, short circuit time does not exceed 30 seconds.
