1Pcs Motor Speed Controller PWM Speed Regulator DC 12V 24V 60V 500W Adjustable Speed Regulator with Stepless Variable Rotary Switch

Using two original high-voltage low-resistance MOS transistors and pre-drivers, supporting high-voltage and high-power, better performance and more stable performance
The digital encoder knob adjusts the motor speed, which is more accurate than ordinary potentiometers
Motor soft start function, the current slowly increases when starting the motor, no impact current, effectively protects the motor, and achieves the effect of prolonging the service life of the motor
It comes with a start-stop button and can be controlled by an external switch to meet a variety of control needs. (Note that the external switch should use a self-reset button or button, press once to turn on, and then press to turn off; it cannot achieve always-closed output opening and non-closed output closing Function.)
You can set the duty cycle, the upper and lower limits of the duty cycle, and the operating frequency, which can be operated and used according to the working characteristics of your own motor; with a standard 5135 instrument housing and a back cover for easy installation
