Here is one of my power supplies used to power 7 X 2 amp boards for speaker protection.

All 7 relays take a total current of .875A & this supply will max out at 4A, at which point anymore than this & those 8.2 resisters connected in series with the transformer (not shown) will resist to protect the transformer for a short period of time if needed.
