Welcome to our shop! Introducing our Motor Speed Controller, designed to provide stable and efficient motor control. Key Features: 1. Stable Working: Equipped with two original low resistance MOS tubes and a pre-driver, this controller ensures better stability and supports high voltage and high power. 2. Easier Setting: You can easily set the duty cycle, including the upper and lower limits and minimum change value, to match your motor's working features. 3. Great Accuracy: The digital encoder knob allows for precise motor speed adjustment, offering higher accuracy and consistency compared to ordinary potentiometers, without any drift. 4. Motor Starting: The controller features a soft start function, gradually increasing the current when starting the motor to prevent impact current, effectively protecting the motor and extending its service life. 5. Convenient Uses: It comes with a start-stop button and can be controlled by an external switch. The external switch requires a self-reset button or key, allowing you to turn the motor on and off with ease. 6. Standard Design: The controller is designed to power on by default, and the factory default frequency is 20KHz, suitable for the majority of motors. 7. Easy Installation: With a standard 5135 cover and back cover included, installation becomes much simpler.
