[aprssig] Looking for a power supply

Okay, I'm tired of searching through catalogs and online vendors, for 
something that may not exist...  Maybe someone on the SIG can help.

I need a power supply for an embedded aprs-like device, that gives me 12 
VDC, 48 VDC, and hopefully 24 VAC.

It has to be small, can be open frame even.  Would prefer it takes 
universal AC 100-240 VAC as an input, but 110 VAC only would be fine.

I need about 5 amps for 12 volts, 1 amp for 48 VDC and 1 amp for the 24 VAC 
outputs.

12 volts is for a motherboard, 48 volts is for power-over-ethernet, and 24 
VAC is for a video camera.   The unit has to be relatively small, ideally 
3" x 6" x 2" or less.  And it has to be UL/CE and RoHS compliant.

Right now I'm doing this with two power bricks and a doorbell transformer, 
and it's so embarassing...

And hopefully the solution would be relatively inexpensive, less than $100 
in lots of 10.

Regards,

Mark
