Features: 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 5%-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% Quantity:1PC 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. Package included: 1 x DC 6V - 28V 3A PWM Motor Speed Variable Regulator Controller Switch Package List 1This DC motor speed regulator is highly efficient, accurate and reliable, and has good long-term stability. 2The PWM DC motor speed controller with switch is small in size, low in power consumption and fast in response. 3Using highquality materials, strong and durable, has a long service life. 4The motor speed controller can easily provide a continuous current of 3A to your DC motor or other DC load. 5This DC motor governor has undergone many safety tests and is safe and reliable.
