DC Motor Controller allows controlling the direction of a DC motor using a -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 - - Material: PCB board and metal. - Item size: 32*32mm. - Input supply voltage: 1.8V-15VDC. - The maximum output power: 30W. - The maximum continuous output current: 2A. - The motor controller is with a self-recovery fuse 2A and a Power-On LED light. - Note: This item can’t afford the electrical machine which continuous current more than 0.5A, such as 755 electrical machines and children’s motor cars. 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 1.8V-15V 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 fuse in line with the positive supply in order to protect the circuit from any possible short circuits 3. You can now control the of the motor through potentiometer Package list: 1 * PWM DC 1.8V 3V 5V 6V 12V 2A Adjustable Motor Controller
