It's really frustrating I can't seem to find an actual wiring diagram or a label with enough resolution to make out. The best I could find was quite blurry but it did look like it had some taps. All the good resolution pictures I find are not of that actual unit and do not seem to have taps. Wayne where are you seeing specified that it has taps?

This lists catalog numbers and wiring diagrams:

Some transformers have taps, some don't, and some have taps for different nominal voltages, so if the wiring diagram shows taps you need to double check that these aren't 120/208/240/277.

I've got a small mixer I need to power. It needs 3 phases plus a neutral and my premise system is 240V, thus I need a 240 delta to 380y/220 transformer. The motor is only .75 KW. I can find such a transformer no problem however the smallest one immediately available is 3KVA and a couple grand. It won't be used much and isn't really a prize anyway so I'm just trying to come up with a cheaper option. It's an annoying voltage, he's trying to come up with another more common transformer that would have the same ratio and nothing works. I thought about making up my own Delta/Wye Bank out of single phase control transformers. I would need 240 to 220 volt transformers. Can't even find those. Anybody got any nice creative bastard solution I may have overlooked?

Don't know if you really need a neutral for a small motor, but here is some used oddballs in your price range.

Powertran was a local manufacturer to me and made some quality product.

Are you scared of different voltage numbers? Competent electricians and engineers don't let that get to them.

Why would I be scared scared of systems I have dealt with ?? Would you even know?

I don't even know what that means. You are very vocal about your hatred of different voltages. It is irrational and borderline obsessive. No one here cares how "simple" some voltage in another country on another continent is. We have what we have and do what we have to to make things work.

Hatred ? Really ?? Don't be daft. Perhaps it might help you to know a bit about me - mod's for excuse my distraction. So, Coollwilly, my field was mainly power electronics and did that extensively - including USA. So I do know about the various systems there. That's why prefer prefer the simpler systems we have in the EU.

simple is buying equipment for the country it is made for. You will have similar problems of needing supply conversion if trying to power something not made to run on 400/230;)

I have. In SA, Taiwan, Libya, Canada and quite a few others.

That is a burden you have to take if you wish to design or install things in multiple countries.

For the US a lot of equipment is dual voltage and will work on 240 or 480, or if it is single phase equipment may be dual voltage and will run on 120 or 120 or 240.

Yes, I have that in other countries - including USA

Yeah but even us uncultured tea-thrower-overboarders know that you really use 416/240

If 416/240 is standard for Domestic & Industry that beats what our tea party left US.

You appear every time a voltage other than 400Y/230 is mentioned. It's like an incantation to summon you. But again, no one cares how simple you think it is. We cannot change what is in place and you harping on it every time just makes you look silly. Dur... Simple .. dur... Simple duhhh....
