NIUGUY Switching Converter, AC100V~240V to DC12V 10A, 120W Power Supply Transformer for LED Strip Lights Driver CCTV Camera Security System

Update: My unit failed after a few months, but the seller went out of their way to replace it with a new unit, no questions asked and without requiring me to send in the old one. The new unit is working great and I applaud the manufacturer and seller for making this right. Only way I could see to improve the unit is to have a cover over the A/C screw terminals so that there's no chance of touching the connectors. Otherwise, great transformer. I have 3 of them and they are perfect for use under my kitchen cabinets (LED strip lighting). THANK YOU !

My power supply stopped working on October 15, 2018; I had received the unit on July 22, 2018. I contacted the supplier NIUGUY through Amazon. They responded that electronic products are often affected by the environment in which they are used, and there is a certain minimal failure rate. They are backing their 3 year warranty by sending me a new power supply replacement.

I purchase two of the power supplies and they have worked very well and solved many of my problems with the quality of my DVR's picture. No more waves of dark lines across the picture due to poor ground and low out put of power to the cameras. I've had the two power supplies for about four weeks now and are very happy with them. I can't speak about how they will hold up over time but if I get two years out of them I will be very happy.

I thought the product came with broken (turns out it was only user error). NiuGuy was very quick with his responses, and very helpful making everything right. The product works well and is now being used in my smart bartender!

built my own version of an Arri Skypanel using this psu. Excellent products, quality parts.

Easy to install and wire. Fan is fairly audible, though.

Very clean power. The DC voltage output is adjustable, which is nice. I took a 30 second reading with a Fluke meter and it held steady at 12.43 +/- .02 VDC.

I bought this after another 12V supply I bought on Amazon failed on the second day when the main capacitor blew under a light load, powering 4 CCTV cams. This power supply looks better made with the capacitor bedded in a heat sink compound.Comes well packaged with a spec sheet (which the other PS didn't bother with).

Unit was dead on arrival. Problem was a cold joint on the terminal block on the "L" signal. It is a pity that such a basic flaw was not caught at QC. Disappointing. I will never recommend a manufacturer that can't even spot such a blatant cold joint at QC.
