CATIYA12V 60W LED Driver Transformer, IP67 Waterproof Constant Voltage Power Supply for LED Lights

Bought this to power my LED under cabinet strip light project. I was estimating right at 60W of power at12V but wanted some margin so the power supply would not strain itself and/or run hot in a confined non-ventilated space with my 25 foot wiring runs to 2 of the 3 areas in the kitchen. In general, I would suggest NOT operating any of these type supplies (from any supplier) at more than 80% of their rated capacity, regardless of their safety certification status. Even then, monitor their performance after installation over a few hours.What attracted me to this supply was what looked like a well built extruded outer casing with screw mounting features, AC input with standard U.S. 3 prong plug, and a heavy gauge output pigtail. The outdoor rating was not important to me, but a nice extra given that I was mounting behind a refrigerator with a water line hookup below it. This unit was a few dollars more than some others I was looking at, but those generally did not include the input connector which made up the difference. In my application the case size (height in particular) was also right in the range I wanted it to be. Right out of the box, the unit is impressive in its compact and robust appearance. These "waterproof" outdoor supplies are generally low cost standard switching power supplies that have been pumped full of (thermally conductive?) sealant and this is the same in that respect. You'll see some of that material has filled some of the space in between the case fins around the end plates as it overflowed when they first filled it, but otherwise this unit is very clean and appears solidly built. The casing is an attractive darker gray plating that looks good in case you are going to have this exposed somewhere. All basic specs with connection info are legibly and conveniently etched right into the top. Basically, it looks good and was all if not more than expected.Operation: For a quick test, I connected the DC output wires directly into a 1 meter strip of 5050 sized LEDs and then plugged the unit into a 110VAC wall outlet. It took a few seconds for the internal capacitors in the supply to charge up and then the strip lit up. I did note a slight hum from the supply before I disconnected the LED strip but that was likely due to the power supply not having enough load, about 14% on this first test, to regulate properly. I then connected the supply to a longer run of LEDs giving it more load to work against (about 50W) and this time the supply started up after a shorter delay and there was no hum. Having verified that the supply worked OK and was putting out a nominal 12VDC, I connected the output wires to my LED PWM dimmer/controller and plugged the supply back in. Over about 18 hours with the controller operating 60W worth of LED strips for hours each at 0%, 40% &100%, I have had no issues / no noise / etc. The power supply case is basically neutral or slightly cool to the touch in feel anywhere I touch it, so I haven't bothered to measure actual temperature. SInce the power supply is "on" regardless of my dimmer setting now, there is no delay other than what is normally in my "smart home" network even when I try the manual switch feature on my particular LED controller. If you are powering down the supply from its input side in your application, then there will likely be a short delay when powering back up due to the protective circuits in the design. YMMV in that case.Bottom line: This seems to be a good power supply for the money that should provide years of service when installed and operated correctly.

I wired it up to the existing old plug, and away I went. Powering 3 upper cabinets covered in LED strips. My mother was going to pay 60$ through Grainger for this but they didn't have an exact match, and it would have taken even longer to get here. She couldn't decide which one to get (she's retired age, set in her ways, ways that don't really exist anymore, even here in the laid back country-side) I just went ahead and ordered it anyways. Without saying a thing I hooked it up, and it's still working a month or two later. We use the cabinet LED's as our night-light and they stay on 24/7. This unit has some good weight to it, and an aluminum or metal-like enclosure (read: not plastic, because plastic can burn/melt), so I have some piece of mind with it sitting on-top of the wooden cabinets that it won't cause an issue. Definitely a little above 'builder-grade' quality from what I can tell - just keep in mind, give it 5~10 seconds to power up the first time you plug it in so you can be sure it works. I hit the switch, waited a few seconds and nothing happened, so i flicked it back off to go check the connections, and the lights quickly flashed letting me know it was hooked up right in the first place before I could get to the connections. So when in doubt, wait it out! Wait a good 15 seconds when first testing, though people in the industry would already know this with transformers. I'm just a 'weekend warrior' when it comes to electrical work, knowing just enough to keep the house working and safe.--Would purchase again without hesitation.

I bought this driver and was wondering if this is a dimmable driver.

What you see in the photo is what I received. No box just a power supply in a bag with a piece of white tape on it that says “bad”. I’ve purchased 46 of these over the course of seven or eight months at first they were great over the course of the last month and a half their quality has dropped. I’ve received several bad power supplies and others that failed only a week after being installed. Today was icing on the cake. They sent me a used item in a baggie not even in the traditional box clearly not even trying to push a good product. Steer clear if you want a reliable power supply.

Quality high technology manufacturing at a low price ($25). Heavy duty AC line cord. Runs cool at 6 Amp loading. I added a 7 Amp in line fuse to feed a dozen LED landscape lights. I bought two of these and would buy more if they continue to operate in outside bad weather conditions. A rain protection hood is easily provided. I used 16 AWG 2 wire cable to connect the lights to the power supply.

I used the transformer to power four 50 watt motion sensor lights on our hillside to discourage and see deer headed for our flower bed. I connected a low voltage wire to the transformer and plugged it in to an outside outlet. I have had the transformer now for 3 or 4 months and it has worked great. It is exposed to the elements and has been rained on several times - no problem. I plan to buy another one to add 4 more lights to the hillside.

Good transformer, keep in mind there is no timer. I used a smart plug to power it on and off, works great and does not seem to generate much heat.

Don't know why they want me to rate warmth, and sheerness on this product? LOL It has nothing to do with a transformer.As to the transformer though, it is well made, easy to install and hook up.The output is stable and at the ratings advertised.Quiet and stays cool. Does not have the high pitched hum like the one I tossed in the recycle bin.
