All this talk of Transformers......

That's one of the reasons I've got one. Haven't plumbed it in yet though...

I'd much rather find a 240/415 transformer for a good price, but they don't seem to be as cheap or easy to get retail in on-offs at 2-3kVA sizes.

If you find a source tell us! My homebrew version is running two large 415v to 55-0-55 transformers "in reverse" with series input and parallel outputs (a Pentagrid Jim suggestion). Works OK Transwave will sell you a bare tranny as a start point.

I had a transformer built for my converter by JMS transformers in Peterborough a couple of years ago, they did an 8KVA unit in a floor standing case for £155; they can be contacted by email at snipped-for-privacy@transformers.gb.com (usual disclaimers apply). Martin

Bob,

A few years ago someone here contacted one of the converter companies ("Boost"?) and persuaded them to sell a couple of transformers for a sensible (but not cheap) price - it might be worth a few calls.

Hi Dave & other respondants

Ive been in touch with both a transformer manufacturer (Douglas) and

This is cheaper than Douglas.

I guess this is not too bad a price although more beer vouchers than I currently have to spare for the project. Maybe I could sell the excesses of Christmas socks, handkerchiefs, slippers etc on Fleabay to raise funds?

Bob,

I bought a transformer direct from Transwave a few years back when I made a 10KW converter (I think it's the one Tim Leech now has) - they were excellent to deal with, brought it to the ME show at Wembley (that dates it!) and the chap even lugged it into my car boot as I had a dicky back at the time. I'd done a lot of searching arround and they were the best deal I could find.

Hang on until we move the factory. We used to have some 230/415 trannies for some spot welders that we sold, and I think the transformers may well be lurking under benches in the factory, covered in 20+ years of dead spiders and dust.

I'll have a tentative poke around after Xmas when we move out the coilwinding gear and have a bit of free space.

Transformers (plural)?

Form an Orderly queue!

Mark Rand RTFM

Me too! :-)

Dave

Duly hanging on Peter!!

Thanks in advance

Bob

No promises! but they should still be there, somewhere....

Because the spot welders were 415V single-phase input, we had to have the trannies made to run them off 240V 13A sockets, and when the welders went I am sure we didn't let the transformers go with them.

We've been in the factory since it was new, 23 years this coming Xmas....

Seems like yesterday....

Peter I'm putting my hand in the air aswell! Count me in if you find a horde.

Charles

Indeed. Should you find a horde, I could be interested too :-).

Chris

Andrew, would that have been the converter that I gave you a whole load of capacitors in exchange for a 3 phase motor for my compressor a good few years ago? Your post just stirred my memory Bob

I guess if we actually had a horde, we'd be looking for two new factories, not one!

New place is just round the corner from where we live, so a minute or so to walk to work each morning rather than hour and a half or more and the same at night.

Also nearly twice as big, so room for yet more junk.... :-))
