PWM Low Voltage Dc 1.8v 3v 5v 6v 12v 2a Motor speed controller 1803BK 1803B adjustable driver switch, Pack of 3

• PWM DC speed controller, with switch function, output voltage range DC 2.2V-12V available, applicable current within 2A, power supply voltage: DC2.2-12V.
• Equipped with self-recovery fuse, it will automatically disconnect if the current is too large, and the fuse will automatically recover after cooling.
• Suitable for the speed regulation of DC motor, fan, fish tank oxygen pump and other products in DC1.8V-12V.
• This is a speed governor with a maximum current of 2A. If the continuous current is greater than 0.5A, the 775 motor and the childrens car motor cannot be driven. It is not recommended to supply power greater than 12V, such as a 12V lead-acid battery, which may cause damage to the governor.
