Motor Speed Controller PWM DC 12V 24V 60V 500W Adjustable Speed Regulator with Stepless Variable Rotary Switch PWM Signal Generator Driver Module

Properties: 1. Equipped with start-stop button, and can be external switch control, to meet various customer control requirements. (Note: The external switch should use the self-reset button or key, press to open and then press to close;it can't realize the function of opening output when it is closed all the time, and closing output when it is not closed.) 2. Motor soft start function. When starting the motor, the current increases slowly and there is no shock current, which can effectively protect the motor and prolong its service life. 3. Duty cycle, duty cycle upper and lower limits and working frequency can be set to facilitate customers to operate and use their motors according to their working characteristics. 4. Digital encoder knob adjusts motor speed, which is more accurate and consistent than ordinary potentiometer. 5. With standard 5135 instrument shell, convenient for customer installation. Application: Drive motor Brightness control Speed control Generator Parameters: Working voltage: DC 9V-60V Rated current: 12A Peak current: 20A Power: 500W (max.) Working Frequency: 1KHz-99KHz Frequency Accuracy: 1% Frequency Resolution: 1KHz Working cycle: 0%-100% Working cycle resolution: 1% Working Temperature: -40~85°C Working humidity: 0%-95%RH Size: 79*43*26mm Operation of digital encoder knob: 1. In the default interface: (the duty cycle is displayed by default) Short press: switch motor start and stop Long press 10s:  to enter the setting interface Counterclockwise rotation: the duty ratio decreases Clockwise rotation: increased duty cycle 2. Under the setting screen: Short press: select setting parameters and switch between ON-OFF, duty cycle lower limit, duty cycle upper limit and working frequency. ON-OFF is to set the module to
