Technical Parameters:n nworking voltage: DC9V~60V, input anti-reverse connection protectionnrated current: 12A maximum current 20Anmaximum power: 500Wnworking frequency: 1KHz~99KHz adjustable, 1KHz step, default frequency of 20KHz, accuracy of about 1%nduty cycle: 0-100%, 1% stepnproduct size: 79mm*43mm*26mmnInstall hole size:76.5mm*39.3mmnproduct weight: 43g(Naked heavy)65.5g(With the packing)nAll parameters can be set to power down storagennOperation of digital encoder knobnIn the default interface :(the duty cycle is displayed by default)nShort press -- switch motor start and stopnLong press 10s -- to enter the setting interfacenCounterclockwise rotation -- the duty ratio decreasesnClockwise rotation -- increased duty cyclenUnder the setting screen:nShort press -- select setting parameters and switch between ON-OFF,duty cycle lower limit, duty cycle upper limit and workingnfrequency. 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.nLong press 2s -- exit the setting interfacenCounterclockwise rotation - the corresponding Settings are reducednClockwise rotation - the setting parameters increase accordinglyn nThe stop button interface on the backnExternal 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.
