Features
1. Using two high-voltage and low-resistance MOS tubes, as well as the pre-driver, the performance is more stable and supports high-voltage and high-power.
2. The duty cycle, the upper and lower limits of the duty cycle and the working frequency can be set, which is convenient for customers to operate and use according to the working characteristics of their own motors.
3. The digital encoder knob adjusts the motor speed, which is more accurate and consistent than ordinary potentiometer adjustment, and will not drift.
4. Motor soft start function, the current increases slowly when starting the motor, no inrush current, effectively protects the motor and prolongs the service life of the motor
5. It has its own start and stop button, and can be controlled by an external switch to meet various control needs of customers. (Note that the external switch should use a self-reset button or key, press it once to turn on, and then press it to turn off; it cannot be closed all the time and the output is turned on, no The function of closing the output off.)
6. With standard 5135 instrument shell and back cover, it is convenient for customers to install.
Technical parameter:

All settable parameters are stored after power-off
Digital encoder knob
Under the default interface: (the duty cycle is displayed by default)
Short press - switch motor start and stop
Press and hold for 10 seconds - enter the setting interface
Rotate counterclockwise - reduce duty cycle
Clockwise rotation - increased duty cycle
Under the settings interface:
Short press - to select the setting parameter, the setting parameter can be switched between ON-OFF, lower limit of duty cycle, upper limit of duty cycle and operating frequency. ON-OFF means that the module is normally open or normally closed by default at power-on. The lower limit of the duty cycle is displayed in the form of "L" + two digits, and the upper limit of the duty cycle is displayed in the form of "H" + two digits or "100". The frequency display form is "F" + two digits.
Press and hold for 2 seconds - exit the setting interface
Rotate counterclockwise - the corresponding setting parameter decreases
Rotate clockwise - the corresponding setting parameter increases
STOP port on the back
It can be connected to an external switch button or 3.3V level. Do not use it in a complex electromagnetic environment. There is no relevant protection inside the circuit. (Note that the external switch should use a self-reset button or key, press it once to turn on, and press it again to turn off; the function of always closing the output to turn on and not closing the output to turn off cannot be realized.)
