Speed Regulator Controller Switch 3a 12v/24v/36v Pulse Width Pwm Dc Motor

100% brand new and high quality Control the speed of a DC motor with this controller. Control the light of a lamp with this controller. High efficiency, high torque, high power, high heat dissipation. With overcurrent protection. The high quality COMBICON improve the stability of circuit. Input voltage: DC12V - 36V Sustained current:3A,max.6A(Need to add a cooling fan when max. current) PWM Duty Cycle:0 -100% Material: Plastic, metal Size (L*W*H):55mm*35mm*21mm Note: Due to the difference between different monitors, the picture may not reflect the actual color of the item. Thank you To connect the DC power supply:ensure the power supply voltage 12V - 36V, ensure the power supply output power meet the requirements of the motor work.Dc power don't reverse the positive and negative terminals, otherwise the governor may damage; Line connecting motor: the motor can be both positive and negative, when running direction and expectations are not consistent, can adjust the line sequence by position or to change the direction; Adjust potentiometer knob: adjust potentiometer knob can change speed output duty cycle, motor speed change.
