5A PWM Driver Module


DC Motor Speed Controller, the full name of pulse width modulation is Pulse Width Modulator. Abbreviation PWM. DC motor governor is a device for adjusting the speed of a DC motor. DC motor has the characteristics of low speed and large torque which can not be replaced by the AC motor. Therefore, the equipment that regulates the speed of the DC motor - DC governor can be widely used.

It is often used in DC load circuits due to its special properties. Lamp dimming or DC motor speed regulation, HW-1020 governor are made by pulse width modulation (PWM) principle. Such as Motor governor and PWM governor. Industrial DC motor speed regulation, industrial conveyor belt speed regulation, lighting and lighting mediation, computer power supply cooling, DC fan, etc., have been widely used.


Input voltage: DC 6-30V

Load power: 90W(MAX)

Rated current: 5A(MAX)

Speed range: 1%-100%

PWM frequency: 10Khz

Potentiometer: resistance value 100K

Knob inner diameter:8mm

The output voltage is 0-100% of the input voltage

Standby current:0.015A

Size(without Knob): 30*24*19mm


Using Steps:

Turn the potentiometer counterclockwise until you hear the sound from potentiometer

Connect DC motor or lamp which meets the requirements at ‘MOTOR+’ and ‘MOTOR-’

Connect DC power supply at ‘DC IN+’ and ‘DC IN-’

Adjust knob to control speed for motor

If need to stop, you can turn the potentiometer counterclockwise until you hear the sound from potentiometer

Remove power supply before remove DC motor

Remove DC motor


Industrial DC motor speed regulation

Industrial conveyor belt speed regulation

Lighting and lighting mediation

Computer power supply cooling

DC fan


It is working for DC motor and just can connect to DC power supply. So please don’t connect AC 110V or 220V power supply! Otherwise it will damage the module!

The positive and negative poles of the DC power supply can not be reversed, Otherwise the governor will damage

Motor can be divided into positive and negative, when the direction of operation and expectations are inconsistent, you can change the direction of the alignment

The potentiometer knob can change the output duty cycle of the governor, thus changing the speed of the motor

Please allow 1-3mm differs due to manual measurement


High frequency 10Khz, the purer the signal

PWM can be adjusted 1%-100%

Support high current

High quality knob

Knob integrated design

No polarity regulation

Kit include:
