This motor speed controller uses two original MOS tubes with low internal resistance and a previous stepper driver, which provides better performance and more stable performance, and supports high current and high frequency. It comes with a startstop button and can be controlled by an ether switch to meet the control needs of customers.The motor speed controller can set the minimum value, ma value and working frequency, which is convenient for customers to use and use according to their own motor or LED working characteristics. Setting the minimum value avoids the situation that the motor does not rotate or the light does not light up with the value, and setting the ma value avoids the situation that the motor runs too fast or the LED lights up too brightly when displaying 100.This motor speed controller 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 that you 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 the needs of different customers. It can be adjusted slowly and finely, or quickly and roughly. The start time and stop time can be set to 0.09.9 seconds, the motor is softstarted, no surge current, effectively protecting the motor and extending the life of the motor.The PWM motor speed controller with standard 5135 instrument housing and back cover, which is convenient for customers to install.Material ABSElectronic componentsColor blackPackage contents1Engine speed controllerOnly the above package contents, other products are not included.Note Light and different displays may cause the color of the item in the picture to be slightly different from the real thing.
