10A PWM motor speed control board cannot mediate high power DC motor stepless speed regulator
Note: this controller provide 70% of input voltage and control only 70% to 100%, it does not control 0% to 100%, if you full voltage control better change the variable
This speed control board has a speed range of 70-100%.
The motor cannot be stopped or adjusted, and an external power switch is required to start and stop the motor.
It is suitable for voltages of 7-12V and drive currents of 10A.
