PWM DC motor governor 9-60v /12A/500W motor fan controller 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. Why does a motor governor use a digital encoder knob instead of a normal potentiometer? 1. Product highlights: 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.) 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. 1.4 digital encoder knob adjusts motor speed, which is more accurate and consistent than ordinary potentiometer. 1.5 with standard 5135 instrument shell, convenient for customer installation. 2. Technical parameters: 2.1 working voltage: DC9V~60V, input anti-reverse connection protection 2.2 rated current: 12A maximum current 20A 2.3 maximum power: 500W 2.2 working frequency: 1KHz~99KHz adjustable, 1KHz step, default frequency of 20KHz, accuracy of about 1% 2.3 duty cycle: 0-100%, 1% step 2.4 product size: 79mm*43mm*26mm Install hole size:76.5mm*39.3mm 2.5 product weight: 43g(Naked heavy)65.5g(With the packing) 2.6 packaging: carton packaging All parameters can be set to power down storage 3. Operation instructions: 3.1 wiring instructions 3.2 operation of digital encoder knob 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 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 be normally open or closed by default. Rotate the encoder to switch to the default on-off state.The display form of duty cycle lower limit is "L" + two digits, the display form of duty cycle upper limit is "H" + two digits or "100", and the display form of working frequency is "F" + two digits. Long press 2s -- exit the setting interface Counterclockwise rotation - the corresponding Settings are reduced Clockwise rotation - the setting parameters increase accordingly 3.3 The stop button interface on the back External switch keys or 3.3v level.Do not use in complex electromagnetic environments because there is no protection inside the circuit.(note that the external switch should use the self-reset button or key, press to open and then press to close;It cannot realize the function of output on when the switch is always closed and output off when the switch is not closed.
