Sorry, but I don't know enough about electronics to design a power supply circuit to power my SX 28.  I need a very small circuit 

to convert 120 VAC to DC 5V, with just enough ma to power up the SX28 and one solid state relay.

How much power does the SX actually use up, with the relay,  I can't seem to figure this out.  Would it save space in my design to build a 

transformer circuit that exactly fits the amount of power needed?  i.e. Smaller transformers??  I need the entire circuit, power 

supply, sx28 and relay to fit in a small plastic enclosure, thats why I can't use a regular wall wart.
