This is DC motor controller, please make sure the input voltage is from DC power, do not use home 220V AC, otherwise it will burn out.
The DC Motor Speed Controller allows controlling direction of a DC motor using a Pulse-Width-Modulated (PWM) DC voltage with a Duty Cycle fully adjustable from 10%-100%. The motor speed controller can provide a continuous current of 8A to your DC motor or other DC load.
100% brand new and high quality.
