Mini PWM DC Motor Speed Controller 3-35V 5A 90W with Resettable Fuse
The Mini PWM DC Motor Speed Controller 3-35V 5A 90W is a compact pulse-width modulation (PWM) controller designed to efficiently adjust the speed of brushed DC motors while minimizing power loss. By varying the PWM duty cycle instead of directly reducing the supply voltage, the controller provides smooth motor speed adjustment while maintaining efficient operation.
The module features a built-in resettable (self-recovery) fuse that helps protect the circuit against overcurrent and overload conditions. If excessive current causes the fuse to trip, it temporarily interrupts the circuit and automatically resets after the overload is removed and the fuse has cooled down.
Its compact size and simple operation make it suitable for hobby, robotics, automation, and DIY electronics projects. An onboard rotary potentiometer provides convenient speed adjustment, while screw terminals allow easy connection to the DC power supply and motor.
