DC 5 to 15V 18A motor speed controller PWM

The speed control board voltage range: DC5V-18V

Rated current 12A, short current 15A. it can provide the power on 5 V 60W , 6V 70W, 9V  110W, 12V 150W, 15V 180W withi and 18V200W.

PWM output range: 0 % -100% , the motor can be fully controlled and get the highest speed operation.

Frequency: 13kz

Speed ??control board has a power supply voltage reverse polarity protection,
Speed ??control board with slow start function, within 2 seconds to the motor can get full speed,

Speed ??control board can be controlled with an external 5V 10KHZ PWM signal from Arduino or any other MCU.
