PWM DC motor controller, motor speed regulator, LED light dimmer, digital display encoder, 5V 12V 24V

1. Equipped with an on/off button and an external switch control to meet various customer control requirements.

2. Soft-start motor function. When the motor starts, the current increases slowly, and there is no inrush current, which can effectively protect the motor and extend its service life. 3. Duty cycle, upper and lower duty cycles, and operating frequency can be set to allow the customer to operate and use their motor according to its operating characteristics. 4. The digital encoder knob adjusts the motor speed, which is more precise and consistent than ordinary potentiometers. 5. With a standard 5135 instrument enclosure for customer installation.

Specification:

Item Type: Motor Controller.

Operating voltage: DC5V ~ 30V, input reverse current protection. Rated current: 5A, maximum current 15A. Maximum power: 150W. Working frequency: 1kHz ~ 99kHz adjustable, 1kHz increments, default frequency 20kHz, accuracy approximately 1%. Duty cycle: 0-100%, 1% increments. Product size: 79 x 43 x 26 mm / 3.11 x 1.69 x 1.02 inches. All adjustable parameters are disabled. Package list: 1 module. Note: Digital encoder button operation: In the default interface (default duty cycle display): Short press - motor start and stop. Long press - enters the settings interface. Counterclockwise rotation - reduces the duty cycle. Turn clockwise to increase the duty cycle. Below the settings screen: Press briefly to select the defined parameters and switch between the lower duty cycle limit, the upper duty cycle limit, and the working frequency. The lower duty cycle limit is displayed as L + two digits. The upper duty cycle limit is displayed as H + two digits or 100. The working frequency is displayed as "F" + two digits. Press and hold to exit the settings interface. Rotate counterclockwise to decrease the corresponding parameters. Rotate clockwise to increase the parameter accordingly. After the STOP port, the key can be turned open or the 3.3V level can be connected externally. When the key is turned off or the 3.3V level is lowered, the motor's start/stop state is switched.
