PWM Motor Speed Controller 5V 9V 12V 24V 30V DC 5V-30V Pulse Width Modulation Regulator 5A 150W Stepless Variable SpeedForward and Reverse Switch Pulse Width Modulation DC Speed Regulation

? Product Highlights: ? 1.1 Equipped with start-stop button and external switch control to meet various customer control requirements 1.2 motor soft start function. When the motor starts, the current increases slowly, and there is no inrush current, which can effectively protect the motor and prolong the service life. 1.3 Duty cycle, upper and lower duty cycle and operating frequency can be set to allow the customer to operate and use the motor according to its operating characteristics. 1.3 Digital encoder knob can adjust the motor speed, which is more accurate and consistent than ordinary potentiometer. 1.4 With standard 5135 instrument housing, convenient for customer installation. ?Technical parameters: ? 2.1 Working voltage: DC5V~30V, input anti-reverse protection 2.2 rated current: 5A maximum current 15A 2.3 Maximum power: 150W 2.2 Working frequency: 1KHz~99KHz adjustable, 1KHz stepping, default frequency 20KHz, accuracy about 1% 2.3 duty cycle: 0-100%, 1% stepping 2.4 Product Size: 79mm * 43mm * 26mm 2.5 Product Weight: 41 g 2.6 Packaging: carton packaging All parameters can be set to turn off the power. 3. Operating instructions: 3.1 wiring instructions 3.2 Digital encoder knob operation In the default interface: (default display duty cycle) Short press - switch motor start and stop Long press - enter the settings interface Counterclockwise rotation - duty cycle reduction Rotate clockwise - increase duty cycle ? Under the settings screen: ? Short press - select set parameters and switch between duty cycle lower limit, duty cycle upper limit and work The lower li
