Working voltage: DC9V~60V, input anti-reverse connection protection 2. Rated current: 12A, maximum current 20A 3. Maximum power: 500W 4. Operating frequency: 1KHz~99KHz adjustable, 1KHz step, default frequency 20KHz, accuracy about 1% 5. Duty cycle: 0-100%, 1% step 6. Product size: 79mm*43mm*26mm Installation hole size: 39.3mm*76.5mm 7. Product weight: 43g (bare weight), 65.5g (with packaging) 8. All settable parameters are stored when power is off.\u003c\/li\u003e\n\u003cli\u003e♥ Wiring Instructions: ① Motor start and stop indicator: start light on, stop light off ②Digital tube: display the duty cycle of motor adjustment, upper and lower limit of duty cycle and frequency ③Digital tube: Display the motor adjustment duty cycle, upper and lower limit of duty cycle and frequency\" ④It can be connected to switch signal or 3.3V level signal to control the start and stop of the motor ⑤ Motor output positive and negative poles Power input positive and negative\u003c\/li\u003e\n\u003cli\u003e♥ Digital encoder knob operation: ①In the default interface: (the default display is the duty cycle) Short press: switch the motor on and off. Press and hold for 10 seconds: enter the setting interface. Counterclockwise rotation: the duty cycle decreases. Clockwise rotation: increased duty cycle.\u003c\/li\u003e\n\u003cli\u003e♥②Setting interface: Short press: select the setting parameter, the setting parameter can be switched between ON-OFF, duty cycle lower limit, duty cycle upper limit, and operating frequency. ON-OFF is the default module power-on normally open or normally closed, the lower limit of the duty cycle is displayed in the form of \"L\" + two digits, and the upper limit of the duty cycle is displayed in the form of \"H\" + two digits or \"100\", the operating frequency Displayed in the form of \"+two digits\".\u003c\/li\u003e\n\u003cli\u003e♥STOP port on the back: It can be connected to external switch buttons or a 3.3V level. Do not use it in complex electromagnetic environments, and there is no relevant protection inside the circuit. (Note that the external switch should use a self-reset button or key, press it once to turn it on, and press it again to turn it off; it cannot realize the function of always closing the output to open, and not closing the output to close).\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eFree shipping on orders $50+. 30-day hassle-free returns.\u003c\/p\u003e","brand":"Belmont Warehouse","offers":[{"title":"Default Title","offer_id":43377933844689,"sku":"BW-B0B393M4PS","price":17.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/3123\/5793\/files\/61-7NbmbDUL.jpg?v=1791730097","url":"https:\/\/belmontwarehouse.com\/products\/ec-buying-zk-bmg-dc-motor-speed-controller-dc-motor-controller-9v-60v-12a-500w-dc-encoder-pwm-control-adjustable-speed-variable-rotary-switch-pwm-signal-generator-module","provider":"Belmont Warehouse","version":"1.0","type":"link"}
