3pcs Mini DC Motor PWM Speed Controller, DC 5V-35V 5A Speed Adjustable Switch Module, 6V 12V 24V Variable Voltage Regulator

The mini style DC motor speed regulator controls the speed of a DC motor by adjusting Pulse-Width-Modulated (PWM), with the latest low voltage technology.

Voltage range: DC 5~35V, Current range: Within 5A, Adjustable Speed range: 0~100%, PWM frequency: 20khz.

The motor speed controller can easily provide a continuous current of 5A to your DC motor or other DC load; Default disconnection of short circuit point ,it is Applicable to 5-35V input voltage.

It is not only to use for dc motor controls of the speed,but also to use for adjust the LED light.

Note: Please connect this DC controller to DC power supply. Never connect directly to household power supply, or it will be damaged.
