DescriptionThe item is a professional and practical DC Motor 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 controller is with a self-recovery fuse 2A and a Power-On LED light. It can easily provide a continuous current of 2A to your DC motor or other DC load.Features- Color: As Shown.- Material: PCB+Metal.- Item size: 5 x 3.5 x 1cm- Input voltage: DC1.8-15V- Output voltage: linear under load- Output current: 0-2A- Continuous current: 2A- control type: flow adjustment- control mode: potentiometer (linear)- range: 0 - 100%- Wiring type: fence terminal block- Potentiometer according to the opening: 7MM-Equipped with self-recovery fuse 2A and a Power-On LED light.- It can provide a continuous current of 2A to your DC motor or other DC load.- Safe protect: If the current is too large, it will be automatically disconnected, and the fuse will automatically recover after cooling.-Warm Tip: Dear buyer, Due to lighting effect, monitor's brightness, manual measurement and etc, there could be some slight differences in the color and size between the photo and the actual item. Sincerely hope that you can understand Thank you Operating instruction1. Connect your DC motor (or DC load) to the motor terminals as indicated on thewiring diagram.2. Connect a voltage of 1.8V-15V DC to the circuit making sure of the correct polarityof the connection. Note that the voltage applied to the motor will be supply voltage applied to thecircuit. It is recommended to add an appropriately rated fuse in line with the positive supplyin order to protect the circuit from any possible short circuits.3. You can now control the of the motor through potentiometer.Important NotesAn appropriately rated fuse (rated a little higher than the maximum current you expectto draw) is recommended to ensure safe operation.The controller is safe with a self-recovery fuse 2A. It will be damaged if connect the supply voltage withwrong polarity. Double check all connections before applying power and always turnoff the power supply before making any wiring changes.
