5V - 28V 3A PWM Motor Speed Controller DC Dimer With Switch (Multicolor)

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 0%-100%. Pulse width modulation (PWM) is a powerful technique for controlling analog circuits with a microprocessor's digital outputs. PWM is employed in a wide variety of applications, ranging from measurement and communications to power control and conversion. Analog circuits.The motor speed controller can easily provide a continuous current of 3A to your DC motor or other DC load.3Volt to 28Volt 3A PWM Speed Control are Use For DC Motor's Speed Controlling or High power LED's Light Controlling.
