Check the listing for details. 9-60V/12A /500W DC Motor Speed Controller PWM w/ Signal Generator Driver Module. Condition: New. Listed at 13.65 USD. 【Soft-s【Soft-start protection】 The motor controller has a soft-start protection function that can effectively reduce the inrush current, protect the motor and prolong the life of the motor.tart protection】 The motor controller has a soft-start protection function that can effectively reduce the inrush current, protect the motor and prolong the life of the motor. 【Digital Encoder Button】 The digital encoder knob can adjust the motor speed, which is more accurate and consistent to control the engine speed than ordinary potentiometers. 【Features】 The duty cycle maximum and minimum limits can be set, as well as the PWM output frequency. 【Wide Input Voltage Range】 This PWM DC Motor Speed Controller supports a widely input voltage from DC 9V-60V, and it fits to 12V 24V 36V 48V power supply, at the same time the output current is 12A, power 500w, which ensures a widely application. You can use this Adjustable Motor Controller in different occasions upon different purposes. Product Description Properties: 1. The knob can be pressed down to control the start and stop of the output. In addition, there is an external control switch at the back of the board (you need a quick reset button or key) to reserve the interface.(Note: The external switch should use the self-reset button or key, press to open and then press to close;it can't realize the function of opening output when it is closed all the time, and closing output when it is not closed.)2. Motor soft start function. When starting the motor, the current increases slowly and there is no shock current, which can effectively protect the motor and prolong its service life.3. The duty cycle maximum and minimum limits can be set, as well as the PWM output frequency.4. Digital encoder knob adjusts motor speed, which is more accurate and consistent than ordinary potentiometer.5. With standard 5135 instrument shell, convenient for customer installation.Operation of digital encoder knob:1. In 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 cycle2. Under the setting screen:Short press: select setting parameters and switch between ON-OFF, duty cycle lower limit, duty cycle upper limit and working frequency.
