★Product Highlights: 1. Using two original high-voltage and low-resistance MOS tubes, as well as the front-end driver, the performance is better and more stable, and it 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 users to operate and use according to the working characteristics of their motors. 3. The digital encoder knob adjusts the motor speed, which has higher precision and better consistency than ordinary potentiometer adjustment and will not cause 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 start and stop button, and can be controlled by an external switch to meet various control needs of users. (Note that the external switch should use a self-reset button or key, press it once to turn it on, and then press it again to turn it off; it cannot be realized that it is always closed and the output is turned on. Do not close the output of the function.) 6. With a standard 5135 instrument shell and back cover, it is convenient for user to install. ★Product parameters: 1. Working voltage: DC9V~60V, input anti-reverse connection protection 2. Rated current: 12A, maximum current 20A 3. Maximum power: 500W 4. Operating frequency: 1KHz~99KHz adjustable, 1KHz step, default frequency 20KHz, accuracy about 1% 5. Duty cycle: 0-100%, 1% step 6. Product size: 79mm*43mm*26mm Installation hole size: 39.3mm*76.5mm 7. Product weight: 43g (bare weight), 65.5g (with packaging) 8. All settable parameters are stored when power is off.

• ♥②Setting interface: Short press: select the setting parameter, the setting parameter can be switched between ON-OFF, duty cycle lower limit, duty cycle upper limit, and operating frequency. ON-OFF is the default module power-on normally open or normally closed, 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 operating frequency Displayed in the form of "+two digits".
• ♥STOP port on the back: It can be connected to external switch buttons or a 3.3V level. Do not use it in complex electromagnetic environments, and 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 it on, and press it again to turn it off; it cannot realize the function of always closing the output to open, and not closing the output to close).
