DC 6V - 28V 3A PWM Motor Speed Varible Regulator Controller Switch

DC 6V - 28V 3A PWM Motor Speed Varible Regulator Controller Switch NEW Y1

This DC Motor   Speed Controller allows controlling the direction of a DC motor using a   Pulse-Width-Modulated (PWM) DC voltage with a Duty Cycle fully   adjustable from 0%-100%.                     The motor speed controller can easily provide a continuous current of3A to your DC motor or other DC load.                     Main technical parameters:                     Input supply voltage:6V-28VDC                      | The maximum output power: 80W                     The maximum continuous output current :3A                     Duty Cycle adjustable:5%-100%                                                             Operating instruction:                     1. Connect your DC motor (or DC load) to the motor terminals as indicated on the wiring diagram.                     2.   Connect a voltage of 10V-36V DC to the circuit making sure of the   correct polarity of the connection. Note that the voltage applied to the   motor will be supply voltage applied to the circuit. It is recommended   to add an appropriately rated fuse inline with the positive supply in   order to protect the circuit from any possible short circuits.                     3. You can now control the speed of the motor through potentiometer.
