5A Motor Speed Controller (PWM) Kit Review

5A Motor Speed Controller (PWM) Kit Feature

• LED brightness to indicate speed
• Adjustable speed via built-in pot
• Compact size for easy integration
• Electronic kit - Assembly required

This DC motor speed controller uses the popular 555 Timer Integrated Circuit to generate a Pulse-Width-Modulated (PWM) output voltage with adjustable duty cycle in order to control the speed of a DC motor without sacrificing torque. Incorporating a high power MOSFET with a heat sink, this controller can easily provide a continuous current of 5A to your DC motor or other DC loads such as high-power LEDs or LED strips for dimming applications. The circuit also includes an LED speed indicator - the brightness varies in proportion to the relative speed of the motor, giving you a handy indicator of the current speed. The PWM frequency is approximately 140 Hz, with the Duty Cycle adjustable from approximately 1% to 99%. From CanaKit.
