AC to AC Wall Transformers

AC-AC wall adapters, aka wall transformers or "wall warts" are available in various voltage and current configurations. AC-AC adapters are unregulated transformers that change 120 Vac to another, lower voltage ie. 4.5Vac, 6Vac, 12Vac, 24Vac. Because they are unregulated the actual voltage will fluctuate depending on the load. The output load is always higher than listed because it drops to the correct voltage when in use, so it is a good idea to get an AC-AC wall transformer that operates close to the desired current.
