Pulse-width modulation (PWM), is a modulation technique that conforms the width of the pulse, formally the pulse duration, based on modulator signal information. Its main use is to allow the control of the power supplied to electrical devices, especially to inertial loads such as DC motors.
This Pulse Width Modular can be used to adjust the duty of PWM range from 10% to 100%. It is high efficiency and has less heat. The max output current can be up to 10A to ensure a large torque, can be widely used in industrial production,
