【Parameter】DC motor speed controller voltage range: DC 4.5~35V, Current range: 0-5A, Adjustable Speed range: 1%~100%, PWM frequency: 20khz, Output power: 90W, Quiescent current: 7u A (standby state). 【Safe to use】This speed controller equipped with a high voltage and high current resettable fuse, ensuring automatic disconnection in case of overcurrent. 【Adjustable speed】The DC Motor Speed Controller controls the speed of a DC motor by adjusting Pulse-Width-Modulated (PWM).Adjust the potentiometer knob to change the governor output duty cycle, the motor speed changes. 【Application】The motor speed controller can easily provide a continuous current of 5A to your motor or other dc load, default disconnection of short circuit point ,it is Applicable to 5-35V input voltage. 【Note】1.DC motor governor input is DC, can not directly connected to the AC (for example: home 220V AC), otherwise it will burn. 2.The positive and negative terminals of the DC power supply are not reversed, otherwise the governor may be damaged. 3.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.
