5A PWM DC Motor Speed Regulator (3V–35V)

The 5A PWM DC Motor Speed Regulator is a compact and efficient module designed to control the speed of DC motors using Pulse Width Modulation (PWM) technology. It supports a wide input voltage range from 3V to 35V and provides up to 5A continuous output current, making it ideal for hobby projects, DIY electronics, robotics, and industrial motor speed control applications.

Specifications:

• Input Voltage: DC 3V – 35V

• Output Current: Up to 5A

• Control Method: PWM (Pulse Width Modulation)

• Power: Up to 90W (depending on voltage/current)

• Adjustable Speed Control Knob

• Compact PCB with heat dissipation design

• Quiescent Current: 7uA (standby)

• PWM Duty Cycle: 1% – 100%

• PWM Frequency: 20kHz

• Dimensions: 30mm x 26mm x 14mm (without knob)

Applications:

• DC motor speed control in robotics and automation

• Electric fans, pumps, and toy motors

• DIY electronic projects requiring motor regulation

• Industrial equipment requiring variable speed motors

Note:

DC motor governor input is DC, 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, the motor speed changes.
