PWM Motor Speed Controller Adjustable Speed Regulator DC 5V-30V 12A 360W Motor Governor with Dual MOS DriverThis motor speed controller uses two original low internal resistance MOS tubes and a preceding stage driver, which has better performance and more stable performance, and supports high current and high frequency. It comes with a start-stop button and can be controlled by an external switch to meet control needs of customers. The motor speed controller can set the minimum value, maximum value and working frequency, which is convenient for customers to operate and use according to their own motor or LED working characteristics. The setting of the minimum value avoids the situation that the motor does not rotate or the light does not turn on with the value, and the setting of the maximum value avoids the situation that the motor is too fast or the LED is too bright when displaying 100. This motor speed regulator uses a digital encoder knob to adjust the motor speed. Compared with ordinary potentiometers, it has higher precision, better consistency and no drift. In this case, you can express to adjust to the value you want. The adjustment step value of this motor speed controller can be set from 0.1 to 25 to meet different customer needs. It can be adjusted slowly and finely, or quickly and roughly. The start time and stop time can be set to 0.0-9.9 seconds; the soft start of the motor, no impact current, effectively protects the motor and prolongs the service life of the motor. The PWM motor speed controller with standard 5135 instrument casing and back cover, which is convenient for customers to install.
