PWM Low Voltage Dc Motor Speed Controller, DC 4.5V-28V Rate Control Driver Switch Adjustable Voltage Electrical Regulator Ultra Small LED with Control Knob Dimmer for Fan Fish Tank Oxygen Pump

About this product

*[Wide Application Small PWM Motor Speed Controller]: The dc motor driver can be used to brush motor speed regulation, light dimming regulation in the DC circuit, fans,fish tank oxygen pumps, very tiny to be wiedly used, not only to use for dc motor controls of the speed, but also speed controller 12v can be used for adjusting the LED light; Note: The 12v motor speed controller cannot be used in electric vehicles

*[PWM Controller with Excellent Heat Dissipation Performance]: The enclosure of the speed controller for the motor is an aluminum enclosure; Equipped with a resettable fuse; Auto disconnected when max.current limit exceeded and self-Recovered after cool down; the aluminum shell of PWM DC motor speed controller is very strong to prevent damage, holes on its side and top of 12 volt variable speed switch are helpful for heat dissipation

*[Easy to Operate Variable Speed Motor]: The stepless motor controller has a simple potentiometer knob adjusts the motor speed from 1% ~ 100% smoothly; and 12v pwm controller with LED display is accurate to show 1 ~ 100% of the motor speed; the input voltage of PWM motor speed controller should be equal to the rated voltage of the motor within 10 55V, or dc motor speed controller will be burnt

*[Speed Control Knob Variable Speed Switch]: The knob has a switch function, 12v fan speed controller can control the motor speed from 1% to 100%; The switch knob is made with great craft of smooth and even damping, for precise adjustment; an adjustable potentiometer flexible cable can be separated, controls the speed of a DC motor with this controller High efficiency, high torque and low heat generation

*[Regulate Range DC Motor]: Mini Style DC Motor Speed Regulator controls the speed of a DC motor by adjusting Pulse-Width-Modulated (PWM); Input supply voltage: DC 4.5V 28V; Maximum current: 5A; Continuous current: 0 5A; Speed range of speed controller for electric motor: 1-100% ; Control frequency: 20KHZ; Quiescent current: 7uA (standby state)
