PWM DC Motor Speed Controller Switch PWM Motor Driver DC 5-30V 150W Adjustable Speed Regulator with Variable Rotary Switch Signal Generator Driver Module

Features:
Power off Memory Function: the motor drive module can automatically save the set parameters, which can effectively prevent data loss after power off. After startup, you can run according to the parameters set last time to improve work efficiency.
Motor Soft Start Function: When starting the motor, the current increases slowly, without inrush current, which effectively protects the motor and prolongs the service life of the motor.
Start-Stop Button Design: Infinitely variable speed controller with a start-stop button design, and can be controlled by an external switch to meet various needs.
Duty Ratio and Working Frequency Can Be Set: DC motor governor can be set duty ratio, upper and lower limit of duty ratio and working frequency, convenient for customers to operate according to their own working characteristics of the motor.
Digital Rotary Encoder: DC brush motor driver adopts digital encoder knob to adjust the motor speed. Compared with ordinary potentiometer, it has good repeatability, high precision, and can be quickly adjusted to the required value.
