Hi,

this is kind of off topic but I assume many of you have to deal with high current applications. I am looking for a better power adapter.

I have a 5V 40A one which has a fan. The fan is very load and even though I use it in a music environment, it sucks.

I would probably get one with even 60 amps instead but I cannot have this load fan any more.

It seems that all fanless ones I find on Aliexpress have open contacts, meaning they are not secure in terms of touching. Its not gonna be installed in a way that it is supposed to be touched but it is still something that could happen (I have children) and therefore I need a secure setup where the high voltage side of the adaptor is in a secure case having a normal cable coming out of it to be either put in a socket or just having open ends so that I could connect them in my own case.

Right now I have this one:

Most other ones look similar to this one and I am not even sure if they have a fan:

A fan as such is ok if it is not too load. I could also use 2 smaller ones if that helps.

I would appreciate if anyone had some advice and maybe there is a way of cabling and securing the power adapters that I have not seen yet. I will mount it in the corner of the room at the ceiling which you normally would not touch…but some kids could jump there…who knows.

The ones like that second one you linked do not have fans. Totally quiet. If you get that type my suggestion would be to put it inside some sort of sturdy project box that has a lid you can screw shut to keep those young fingers away. Putting it inside a project box also creates a convienent place to add an on/off switch, otherwise you have to (un)plug it to turn off/on since it doesn’t have a switch.

You might need to put some vents or small holes in the box for heat dissipation as needed.

Using a sealed project box also prevents tiny fingers getting inside, meaning you can continue using an open-contact power supply.

ok thanks for your comments. i guess i have to put my own box together and use one of those open ones. No switch needed because I have a digital radio controlled switch for the whole circuit. My experience with heat with the 40 amp one is that it only gets warm if I take the full load over a longer time. In my setup typically dont have all LEDs on full white, and if so, just for some strobe effects over a short time. Thanks guys.
