Mini DC 5A Motor PWM Speed Controller 3-35V Speed Control Switch LED Dimmer

This 3V-35V DC PWM DC Motor Speed Regulator is designed as a Mini Style DC Motor Speed Regulator. It controls the speed of a DC motor by adjusting Pulse-Width-Modulated (PWM) DC voltage. It provides a DC voltage with a Duty Cycle fully adjustable from 0%-100%. The onboard potentiometer knob adjusts the change in output duty cycle, as the motor speed changes. In this module, the positive and negative terminals of the DC power supply do not reverse. Otherwise, the governor gets damaged.

As the DC motor governor inputs DC, connecting directly to AC  may cause damage to the module. Moreover, the motor speed controller can easily provide a continuous current up to 5A to your DC motor or other DC load. And also used to drive all DC Brushed Motors that work between  3V-35V DC. Pulse-width modulation (PWM) or duty-cycle variation methods are commonly used in the speed control of DC motors. The duty cycle is defined as the percentage of digital ‘high’ to digital ‘low’ in addition to digital ‘high’ pulse-width during a PWM period.  This is a great method of controlling the amount of power delivered to a load without dissipating any wasted power. The motor can be positive or negative, when the direction of operation and expectations do not match, you can adjust the line order to change the direction.
