For those who don't know what a Rondomatic feeder is, it's a great (but expensive and over-engineered) feeder that unfortunately has been discontinued.
This may be coming too late to be of much assistance, but the power ratings for the Rondomatic 400 US version are 120v 60Hz on the box, and on the transformer it says:
Input: 120V AC/60Hz/0.9VA
Output: 24V AC/7mA
I'm not quite sure if you mean to say that you're going to alter the Euro Rondomatics that you have to run on domestic power, but would like to know if you can make that work.
I tried the opposite approach, and purchased a step up transformer to delver 220V power to the Euro model. I did this to replace my 120V version which had stopped working.
The Euro model with the step up transformer runs too fast, gaining about 4-5 hours per day. This has caused significant water quality problems on long trips. I have no idea if it is a fluke problem with this particular unit, or a power supply/mismatch problem that makes it impossible to use the Euro model at all.
If you can customize the Euro model to work on 120V, would you be willing to do it for a charge?
