Finally, A PWM controller that doesn't leak power when off!
Electrical engineers: This has zero quiescent current when fully switched off (well, close enough to zero that I couldn't measure it with my consumer-grade equipment, at least).I've played with a lot of PWM power controllers. They're extremely useful, except most of them will continuously drain their power source by about 15 to 20 mA even when off, since the onboard chip is always running. This means you can't leave them connected to a battery without killing it when not in use. These are the only kind I found on Amazon that have a power disconnect switch integrated into the potentiometer knob so that when you hear a click, the whole thing is truly off.I am also very hard on my parts and when I torture these PWMs to death, they tend to fail completely rather than partially. I had some others that would develop shorts in the pots that made the controller abruptly cut to 100% output when "off" or low, which can be VERY bad for my applications (and another reason "off" should disconnect power like these do instead of just setting the controller output to a 0% pulse width).

Mine do not match the sales page
Like: has an off position and seems to do what it says.Dislike: knobs are not the minty green I ordered, circuit board looks completely different with different components.Dissatisfied with the color as that was one reason I went with these, I may return and try again.

Works great 👍👍
Only needed one but I'm sure I'll find a use for the rest. I used one of these to control Motor speed on my 3d printed bubble machine for my girls.

Item description is incorrect. Will not work for 5v fans.
This unit does not provide a stable enough frequency to run a fan until it hits 7.5v. before that a 5v fan will simply stutter. Unfortunately I designed a project around this fan controller but Im going to have to go with something else.

Great little controller.
A+ controller, well done.

Great product
Received my package on time. I tested it. Works with my 12V and my 15V power supply to control my fans speeds. Very pleased. Thank you
