Autotransformer for 220v in the UK

Pickledcreeky · 31st August 2005, 11:58 PM

Hello,

Does anyone know where I can get hold of an autotransformer that has a 230v primary and a 220v secondary in the UK?

Thanks in advance!

Kris.

You could custom order these transformers...
What`s the watt rating you are looking for???
And if you don`t mind me asking..what do you need it for??

Well, couldn´t you just link up two 110V-110V Volt ones (like the primaries in series n the same with socondaries), or would´t that work at all?

I had a kind-of-similar problem until last week. I´m from Austria, where we have 220V @ 50Hz. For my ZenLite I needed 110V300W Lightbulbs...defenitely not conviniently available in the alps. I bought them last week in Mexico (surf trip).

Did you post it in an other forum here yet?
Oh, and I´m curious too, what do you need it for?

Greets, David

What is your application? Normally there sis no problem to put in 230 volts into old 220 volts equipment.

Hello all,

I have just picked up a cheap variable transformer today that does the job perfectly. As for the use I have a few pieces of equipment that runs on 220v, The mains at the sockets here is 240v. That was causing the transformers to saturate so I just needed something to take the extra 20v off.

Cheers.

Ok, 240 volts into old 220 V gear may cause problems but you wrote 230 volts....

Sorry I made a mistake but all is fine now anyway (Thought UK had changed to 230v like the rest of europe but still measure 240 at the socket )

Nominally we do use 230V now, but it is still maintained at 240V for compatibility. Since 240V is within the specified tolerance (+10%/-6%), everyone is happy... mostly
