2pcs Pwm Motor Speed Controller Adjustable Regulator with Mos Driver

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.)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 lifeDuty 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.With standard 5135 instrument shell, convenient for customer installation.Parameter:Working voltage: DC 9V -60V, input anti-reverse connection protectionRated current: 12A maximum current 20AMaximum power: 500WWorking frequency: 1KHz~99KHz adjustable, 1KHz step, default frequency of 20KHz, accuracy of about 1%Duty cycle: 0-100%, 1% stepProduct size: 79mm x 43mm x 26mmInstall hole size:76.5mm x 39.3mmOperation of digital encoder knobIn the default interface :(the duty cycle is displayed by default)Short press -switch motor start and stopLong press 10s -to enter the setting interfaceCounterclockwise rotation -the duty ratio decreasesClockwise rotation -increased duty cycleUnder 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.Material: ABScolour: blackPackage Contents:2 x DC 9 -60V 12A 500W PWM DC Motor GovernorOnly the above package content, other products are not included.Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
