he DC Motor Speed Controller (4.5V-35V, 5A) provides precise speed control using PWM technology. It supports a wide voltage range and ensures smooth, efficient motor operation. Ideal for applications such as fans, pumps, electric toys, and automation systems, it features a user-friendly speed control knob for easy adjustment and stable performance.
Precautions:Â DC motor governor input is DC, and can not directly connect to the AC (for example home 220V AC), otherwise, it will burn!
DC power supply positive and negative terminals do not reverse, otherwise, the governor may be damaged.
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.
Adjust the potentiometer knob to change the governor output duty cycle, and the motor speed changes.
