Bought this to use with a hot wire cutter using a 12v power supply. I was maybe drawing about 2-3 amps to get the wire hot enough to cut the foam. The first one I tried worked pretty good. A few days later I tried using it and it wouldn’t adjust the voltage at all. It went full power even when in off position which caused the wire to glow orange. Tried the second one and it failed as did the third one. Maybe I did something wrong but I don’t think do. I would think twice before using it to regulate a hot wire cutter. Maybe a variac would be better. Also, where you plug in the wires can pull out of the case rather easily.

Most importantly: does not cause visual flickering when dimming. Going off my multimeter, at 24V goes from a true 0% to 100% of the input voltage. Seems to be using a ~1.2kHz PWM signal, which does cause Mean Well power supplies to make noise when dimming. Would be nice if it had a higher frequency to avoid that, but for the price it does the job well.

Not much to say. Works as expected, only need to connect the positive wire for most applications. Decent quality plastic. Easy to mount.Best part is they really go through the power curve smoothly. With no jumps or limits--except those from from your LEDs (some don't dim at all, or some just don't like to dim well).Really handy to get three, as I know I'll end up using these a lot.

They work great, but don't hold up against static electric shock. I tried to stay with this product, but must move on.

حلوة بس لمن توزنه على مستوى معيين وتفصل الكهرباء ثم تشبكها يشتغل اقوى شي ويرجع للمستوى الي انت حاطه بس يسويلك هي بلمحة سريحة جدا يمكن البعض لا ينتبه لها

My recent project was adding LED tape into my 3D printer enclosure and those lights are BRIGHT. I really didn't need them to run full blast, so I got these dimmers to tone down the retina searing. Works great! I've wired it directly to my 3D printer's 24V power supply and now I can keep my lights as dim or bright as I need. I stuck it to the side of my enclosure with velcro for easy removal. As others have said, the case for the dimmer is kind of large compared to how little the parts inside are, but it's not a problem. Good product for a reasonable price.

I buy the same type of these as well as water proof strip lights often for the sailboat. About twice a year I have to disassemble and swap parts from an old one, they don't last long, the dimmer fails first, then you have to unplug it to turn it off, then it's just on and off without a dimmer. Don't forget your soldering gun. The reason I buy this product it's CHEAP$. But, always looking for a better product.

PWM dimmers are a simple technology and these are pretty basic looking, but for $3.33 each you can't go wrong. I have installed LED strip lighting for me and for others, and I generally locate these just inside a cabinet door where you don't see them anyway.This dimmer is capable of handling 8 amps of current flow, which is more than enough for one and sometimes two of the typical LED strip reels sold, depending upon LED density. For some reason, the manufacturer likes to place a period (.) after the "V" for voltage on the faceplate, and since that dot precedes the "8A" (the "A" has no period), it makes it appear that this unit is rated at 0.8A when it will actually handle 8A. That's my best guess explanation for the confusion about its current rating.I have had several of these running for as long as a couple of years with no failures yet. For under and over cabinet LED installations, where possible I like to place a regular wall switch in an appropriate location that switches a 120 VAC receptacle that I hide at the back of an upper cabinet. I plug one or more 12 VDC power adapters into this, and place one of these dimmers just behind the cabinet door for each LED circuit I want to be able to adjust. This allows turning the lights on/off just like any other light (e.g., a wall switch that looks like any other) and the LED strips can be set for work light, mood light, or whatever. Hidden inside a cabinet, there's really no reason to spend more on a fancier version with an aluminum box and knob.I'm about to install a few more of these inside the cabinet of an outdoor kitchen to dim landscaping lights. PWM dimmers only work with DC voltage, of course, but all of these lights are powered by a DC supply. This will allow either brighter lighting for guests unfamiliar with step locations and whatnot, or more subtle lighting on a pleasant moonlit night.These are a very inexpensive and useful product that appears to hold up well, at least so far.
