5V-30V Voltage Regulator DC Motor Speed Controller PWM Frequency Duty Cycle E83

5V 12V 24V high power PWM dc motor governor LED dimming module with enclosure, with switch, adjustable frequency, adjustable duty cycle upper and lower limit, MG Why does the motor governor need to set the frequency. Motor governor frequency is too low, power ripple, motor vibration; The frequency is too high, the switch loss is large, the electromagnetic noise is obvious. If the frequency is not chosen properly, the effective power output of the motor will be greatly reduced. The factory default frequency of this product is 20KHz, which can meet most of the motor requirements. Consult motor manufacturer for specific frequency selection. 
 
Features:   
1.1 equipped with start-stop button, and can be external switch control, to meet various customer control requirements. 
1.2 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.
1.3 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. Digital encoder knob adjusts motor speed, which is more accurate and consistent than ordinary potentiometer. 
1.4 with standard 5135 instrument shell, convenient for customer installation.   
 
Specifications:
