I did the same conversion. 24V transformer with fuse is all I added. Other things to note:
- I think all the timers can run on 24v or 120v, not sure if you're planning on changing that too. something to be aware of anyway.
- I put in 1 transformer for every 2 vacs, and also run a couple electronic drop shelf vendors off the same transformer. Bolted the vendors to the light poles on the vac islands, we sell quite a bit of
armor all and tire shine out of them. My point is, think about what else you might want to run off these transformers, and size them accordingly.
- thats all I can think of at the moment
