380v European Equipment

I have a client that is a restaurant owner that already purchased an Italian espresso machine for a new restaurant. The machine requires 380v according to the machine's website. The voltage to our building is 208/3 wye.

I cant seem to find anything on 380v. Im not sure if that is a phase-phase voltage, or if its single phase or 3 phase. Any suggestions on going from 208 to 380v? The load is 3800w.

The website for the machine is below. You just need to click "Read More", and then its "Group 2" which is 3800w total. It does list 220 as a compatible voltage but this is actually a different model machine which is not available in the US. He purchased the 380v already..

Your 380V is a European voltage for a 380Y/220V Wye system at 50 Hz IIRC.

I would imagine it is single phase, L-L, but it could be three phase.

Think if I just said 208V off a 208Y/120V. Could be 1P or 3P, I would have to state which one it is.

A 208V to 380V tannsformer would seem to be the obvious solution.
I would guess single phase.

Yes, it doesen't appear to indicate 3 or single phase on the website either. Im thinking an auto transformer would work.

Anyone know of a manufacturer for this? Google hasnt been yielding good results. Also need to go from 60 to 50 hertz from the looks of it.

It looks like a buck-boost is only good for about a 25% voltage increase. Must be another solution that im missing.

No easy way to do that but the question is if it's even necessary. Site says 220/380 also. Dual voltage? Why don't you give then a call, they do speak English in Australia.

Luckily this client has unlimited funds.

Maybe I just put 3 of these in series? Set each of them for a 22% increase or maybe the first two @ 25% increase and the last for the remainder?

Double wound. i.e seperate windings for the 208 and the 380 windings.
Unless there is anything that is sensitive to frequency, the 50Hz/60Hz may not be an issue.

If it's requires 50 HZ only that could be a problem.

I wonder if using a VFD would be an option?

Everytime I do something like this its a huge problem... I bet anyone that nobody could tell the difference between espresso made from this machihne and one made from an American one..

The problem is that I can only find a boost transformer that will give me about a 26% boost. My voltage is 208 and I need to go to 380 which is an 80% voltage boost. If I could find a transformer capable of giving me an 80% boost with a 208 wye primary, single phase, for a 3kW load, then I would be home free. Kind of hard to come across though.
