4Pcs 12V DC Motor Speed Controller Module Mini 5A 90W PWM DC-DC 4.5V-35V Adjustable Speed Regulator Control Governor Switch DC 6V 12V 18V 24V Drive Mo

DC motor speed controller voltage range: DC 4.5~35V, Current range: Within 5A, Adjustable Speed range: 0~100%, PWM frequency: 20khz<br>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.<br>The motor can be positive or negative, when the direction of operation and expectations do not match, you can adjust the line order to change the direction.<br>Mini dc motor PWM speed controller can adjust the potentiometer knob to change the governor output duty cycle, the motor speed changes.<br>Note: DC motor governor input is DC, can not directly connected to the AC (for example: home 220V AC), otherwise it will burn
