Autotransformer for 220v in the UK
 
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?

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 ):whazzat:

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;)
