COOLM 48V 3A Power Supply Adapter 144W AC 100-240V DC 48 Volt 3 Amp Output Adaptor Interface 5.5 x 2.5mm Plug for PoE Switch PoE Injector Control Systems

So far it works no issues yet will update if I have a problem

I got this to replace our church's WiFi AP POE adapter's supply, which had failed. This one puts out slightly more current (3A vs 2.5A). It has a 3-prong removable AC power cord, while the prior one was only 2-prong. Overall, it seems better constructed and hopefully will last for years.

liked - does the job as advertised, no issue

Made out of Chanisium. Shut off a week into using it. Had to tap it a few times to reset then shut off again after a few more weeks of using it. Not reliable if you're going to use this on your surveillance system...

The adapters made it fit into my Swann NVR. Perfect solution for my bad power supply. Thank you

Only one week in use, it's working good so far. But my application is only a constant 0.6A draw and it runs hotter than I'd expect. (I'd expect it to be cold.) Considering heat is an electronics killer, I hope it lasts.

The 48 volt power supply met my expectations. I would use this supplier again if I need a similar product in the future.

Works great.

llego antes de lo esperado, se ven de buena calidad.
