Package Contents: 2 pieces of PWM DC motor speed controller 1803BK Item specifics: Input supply voltage:1.8V-12VDC The max output power: 30W The max continuous output current : 2A Duty Cycle adjustable: 0%-100% Size: approx. 32*32*12mm Net weight: approx. 14g Note: DC motor speed regulator DC power supply, do not be directly connected to household 220V AC. Please allow 1-3mm differs due to manual measurement. Connect a voltage of 1.8V-12V 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 in line with the positive supply in order to protect the circuit from any possible short circuits. The controller is safe with a self-recovery fuse 2A. It will be damaged if connect the supply voltage with wrong polarity. Double check all connections before applying power and always turn off the power supply before making any wiring changes.
