Some has stated that they don't work. Well the ones I received work as they are intended. No problem at all.

I needed to control fan speed of a PC fan in a DIY project. These worked perfectly. Didn't achieve the full range of the knob as the fan required a minimum amount of voltage to run but worked as expected.

I grabbed these because the motor turning our disco ball spins way to fast. It’s a 3v DC motor. This little unit is small, acts as an on/off switch and I can regulate the ball from about 2 rpm to nearly 12. Just what the doctor ordered. I’ve used units like this before on other projects but this is the smallest I’ve had and works just fine and the price was reasonable.

One of of the two units was bad. I used it to make my rv range fan variable speed. Easy to adapt existing wiring to wire in to the PWM unit.The defective unit did not vary the voltage and only ran off or full speed.

The speed control doesn't consistently work between the 2 I was given. The knob didn't fit tight and falls off.

In an RV the range hood vent fan runs on DC power. None of them have a variable speed fan. That's annoying because it's really easy to control a DC fan. This pwm fan controller is just the ticket. Just drill a 5/16 hole in the sheet metal to mount the knob. This controller is good for up to 2 amps but my vent uses about 1 amp. It has an on board red light that grows in intensity.As you crank the knob but mine is hidden behind the panel anyway.This controller is intended for a dc motor but it can be used for led lights as well.
