I need a 12VDC 3A switching supply (wall wart style)

[dg]

I just need something small enclosure, efficient, and quiet. Can anybody
recommend a good vendor? I only need 2 of them.

Thanks!

Most electronic suppliers can have a 12 V / 3 A supply. You will not
find much bigger than about 1 A in a Wallwart style, due to the weight
and size required.

Bigger than 1 A, it has to be a shelf type.

Look on e-bay, someone seems to always be selling nice power supplies
inexpensively. I got a triple-output 2.5A 5V switched supply for about
$10.

If that fails, you can always find a computer power supply, though I don't
know if that qualifies as quiet. It'll certainly give you the current you
need.

The 3A spec I gave is actually quite a bit more current than I need but I
usually like to keep power supplies operating at ranges at which they are
very comfortable. I don't imagine I will draw more than 1A. I ended up
buying some table top style supplies from DigiKey for $19 each. They put
out 1.5A. They are actually perfect for my application, they are black
boxes with the socket for a standard 3 conductor 110VAC power cord. DigiKey
is great, it has been some time since I last ordered from them. As usual,
they have impressed me with shipping response and huge inventory.

Thanks for the tips!
