Technical Parameters: working voltage: DC9V~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*43mm*26mmInstall hole size:76.5mm*39.3mmproduct weight: 43g(Naked heavy)65.5g(With the packing)All parameters can be set to power down storageOperation 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 workingfrequency. 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 interfaceCounterclockwise rotation - the corresponding Settings are reducedClockwise rotation - the setting parameters increase accordingly The stop button interface on the backExternal 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.
