1803BK DC Motor Speed Controller allows controlling the direction of a DC the motor using a Pulse-Width-Modulated (PWM) DC voltage with a Duty Cycle fully the product adjust from 0%-100%. With a self-recovery fuse 2A and a Power-On LED light. 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 stroller motor will not move. Don't buy it wrong. It is not recommended to supply power greater than 12V, such as 12V lead-acid batteries, which may cause damage to the governor If the current is too large, it will be automatically disconnected, and the fuse will automatically recover after cooling. PWM DC motor speed controller with switch function. Specifications
