Low voltage light transformer for accessory power

A computer power supply will provide over 300 watts at 12 vdc for less than $20, or no cost if you salvage one. Incandescent bulbs don't care if they get ac or dc volts. The power supply also has a lightning fast breaker for direct shorts. I use two on my layout and have 3 amp breakers on the circuits to protect the wiring. You can share the common with your ac without a problem.

That would work except I have a few items that require 12V AC power (vibrator motors), hence why I want to use a transformer with AC output.

Use the computer supply for anything that doesn't need AC, which frees up your Z with 4 variable AC ranges.

If you want to get really tricky, and you are using external breakers, You can use A-B, A-C, A-D, B-C, B-D, & C-D as additional voltage ranges on your Type Z.

Moving those accessories requires rewiring, which I don't want to do. I'd rather just drop in a 300W 12V AC output and be done. If the transformer I linked to will do that with an external circuit breaker/fuse then I'd rather use that.

You can buy 1 or 2 additional type Zs for that $$!
