Woh! That's a 240v to 12v transformer, not 400v but 400va which is 400 volts x amps.
400va / 12v = 33.333amps
400va / 12v = 33.333amps
ive managed to get this transformer off the scrap man for a fiver from what i know of it came from a factory
im considering doing the 3 phase route with it
input is 240v with the connector blocks at the top of transformer output i believe is 400v the 400v side has connected to it 2.5mm wire
i havent tested it as of yet as ive forgotten how to test transformers but i have done electronics before city and guilds 224 part 1 and part 1 year 2
How do you work that out?On a farm, noise not an issue! Then build a generator or buy one, run it on red diesel it will be cheaper than paying the extra electric. My neighbour has a machine shop and after looking into it further its the way forward for rural properties with a 3 phase requirement. I must say going three phase to save money sounds kind of twisted about face because three phase gear will cost more to run, especially the old inefficient stuff
are u talking 3 phase to the cutout fuses and only 2 phases been taken off with single phase meters fitted ??if so thats quite common years ago mainly in large victorian housesAdvantage of 3 phase supply is 3 x the current for single phase stuff...I spoke with SSE a while back and they told me, that unit price is the same generally whether 3 or single phase, standing charge tends to be similar also..
Went into a property, 3 phase head...2 single phase meters..even DNO had no idea why it had been done like that...
4.0KV Motor on a Colchester Master 2500 lathe. I think I now have it all lol
The main reason I need use a CONVERTER as opposed to an INVERTER is because of the wiring on the lathe. If it was a Knacked lathe with no wiring (i.e just a case of spinning a Motor up) the 240 delta configuration on the motor would be useful. I could then use an Inverter. What the problem seems to be is the regulations regarding what INVERTER can use used on mains 240 volt. Most only go up to 3.0KV anyway.
I dont need a Rotary a static will be fine . But even then its £500 or more.
The interesting thing is some info I was told does not fully match with this http://lathes.co.uk/page28david.htm
Seems to be a minefield. lol

Hi Shenion nice to read you!That looks like 240 to 12VAC. 30A out though.
Have you had one? Did you ever use it in anger and was it any good? I cannot actually remember where I got it from, even the £90 was a guess as I got it second hand when I got my mill, I think looking back one of the reasons I never used it was my garage supply can only handle 20 amps tops and this would require more. But now mostly guesswork.That looks very familiar;-)

I have the exact same inverter, made by Transwave. Mine is the 8 hp version and runs my SCM universal woodworking machine. It has 3 seperate 5kw motors for the saw, spindle moulder and planer.Gents, I have posted this on another message and if it will help anyone, then come and borrow it, take it away and play. It is an up to 4 HP static converter, stick a suitable motor on it and you will have a 415 3 phase rotary converter.
I would also have though that some plasma and welders would only be going across two legs of a 3 phase supply therefore, it may be possible to use a step up transformer, guess what is in the static converter.
It is heavy, but I can pick it up OK, but would not like to post it.
It cost me £90 years ago and to be honest has sat under my bench every since as I went to 3 phase 240 volts before I picked it up. It was a, I will do that one day. Not expecting anyone to buy it off me just try and see if the solution works for you.

Just searched my old mail and it seems I flogged it to you in July 2003 and I sent it by dhl, it weighes 24.5kg.
