Ok I am trying to find a really good step down transformer, I just bought some stuff from Japan and the step down transformer is useless it overheats after an hour and shuts itself off.
I need to have it on continousley and wanted to know if there are any sparkies that know more about amps and volts and what where and who//
Thanks guys and gals

il rephrase that, A new store opened in Akihabhara Tokyo its a massive shopping city with everything you can imagine (il post a pic later) and they are selling the most realistic air rifles and guns you can imagine..from pistols to sub machine guns..and these things have the look and weight of the real thing,,really sweet..I would have bought one but Virgin wants you to call them a day in advance before you fly and notify them that you will have this item..but sadly it was a Holiday in Japan so I couldnt get hold of them so that what I meant

Look at the power ratings for all of the devices that you want to run off the transformer (should be in Watts) and add them all together. Then, buy a transformer with a power rating HIGHER (not the same) as that figure.
The only thing to remember is that devices that run on 110v operate at a higher current than those on 240v although the step down transformer should take this into account (made with thicker wires!)

@Cycovision Ok you have confused the hell out of me..so this is rating if you could advise me then this will be handy thanks...
The transformer that needs to run the wireless headphones has the following specs.
Input: AC 100V 50/60Hz 26VA
Output: DC 12V 1000mA
The step down transformer has the following specs
AC110V-130V/220V-240V
MAX=30W
Know I was on the assumption that the 26VA of the transformer would be ok for the 30W on the step down transformer..I guess thats not the case.

EDIT: Just re-read the last post!
The step down transformer and the power supply both operate within tolerences, usually +/- 10%. Even though it should still be fine, I suggest you get 50W step down transformer as it is a little close to the knuckle.

Do you reckon I will be able to leave it on 24/7 or will it burn out..and another option would be to try and find one of those multi voltage adaptors and cut and paste the extension lead for the headphones there..mm then again I better leave that to a pro.
I will check Maplins website and see if they have anything close the 50W bracket and il post my finds back here shortly.

Just found this website which has a calculator but I am not sure what its asking to enter exactly weather it wants the input or output?

Ok I just found this on Maplins site it has a MAX of 100W ( I am guessing the higher the better) sorry to bug you but if you coul have a look that will be cool.

Oh yeah, if you buy a transformer make sure it's got a thermal cut-out
Posted by themarques
Damn you would think things like that come as standard... I better make sure this thing is suspended in the air or something dont want to come back to a burnt home if anything goes wrong.
