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 interface\nCounterclockwise rotation - the corresponding Settings are reduced\nClockwise rotation - the setting parameters increase accordingly\n \nThe stop button interface on the back\nExternal 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.  \u003c\/p\u003e\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan style=\"font-size: 14px;\"\u003e\u003cb\u003ePackage Included:\u003c\/b\u003e\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan style=\"font-size: 14px;\"\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan style=\"font-size: 14px;\"\u003e1 x PWM DC Motor Controller\u003c\/span\u003e\u003c\/p\u003e","brand":"ontproduct","offers":[{"title":"Default Title","offer_id":49120019841249,"sku":"BG-1988319","price":10.79,"currency_code":"HKD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0853\/9317\/8849\/files\/7116ad07-5b5c-4b7e-a607-17798f4274f9.jpg?v=1789396421","url":"https:\/\/ontproduct.com\/products\/pwm-dc-motor-controller-adjustable-speed-dc-9-60v-12v-24v-48v-12a-digital-display-encoder-duty-ratio-frequency-controller","provider":"IvySource","version":"1.0","type":"link"}
