Digital LCD PWM Motor Speed Controller DC 5-30V 5A 150W

ZK-BMG Digital LCD Motor Speed Controller PWM DC DC 5-30V 5A 150W Adjustable Speed Regulator with Stepless Variable Rotary Switch PWM Signal Generator Driver Module.

PWM DC Motor Speed Controller DC 5-30V 5A 150W DC Motor Speed Control ZK-BMG.

Features:
- Two original high-voltage, low-resistance MOS tubes, and front-end drive are used. Enable better performance, supporting high voltage and high power.
- Duty cycle, the upper and lower limits of duty cycle, and operating frequency are settable, which is convenient for users to operate and use according to the operating characteristics of their motors.
- Digital encoder knob adjusts motor speed. Compared with ordinary potentiometers, its accuracy is higher, ensuring better consistency, and no drift.
- Motor Soft-start Function: When your motor is power-on, current increases slowly, without impulse current, which effectively protects your motor and prolongs the service life.
- Designed with ON/OFF button. It can be connected to external switch to meet your needs. (Note: External switch must use self-reset button or button which you can press it once to turn it on, and then press once to turn it off. )
- With standard 5135 instrument housing and back cover for easy installation.

3.2 Digital Encoder Knob Operation:
In the default interface: (the default display is the duty cycle)
- Short press: to turn your motor on and off
- Long press for 10 seconds: to enter into setting interface
- Rotate counterclockwise: to decrease duty cycle
- Turn clockwise: to increase duty cycle

In the setting interface:
- Short press: to select and set parameter. The setting parameter is switched between ON-OFF, lower duty cycle limit, upper duty cycle and working frequency. ON-OFF means the module is normally open or normally closed when power-on. The lower limit of duty cycle is displayed as "L" + two digits. The upper limit of duty cycle is displayed as "H" + two digits or "100". The display format of operating frequency is "F" + two digits.
- Long press for 2 seconds: Exit the setting interface
- Rotate counterclockwise: The corresponding setting parameters are reduced
- Turn clockwise: The corresponding setting parameter increases

3.3 Rear STOP Port:
It can be connected with external switch button or 3.3V level. Do not use it in complicated electromagnetic environment. There is no relevant protection inside the circuit. (Note: External switch must use self-reset button or button which you can press it once to turn it on, and then press once to turn it off. )
