Where to get a Step Down Transformer???

japanpaul

Hi
I'm wondering if anyone knows a shop in Dublin that stocks step down transformers? I am looking for one like this:

http://www.peats.com/cgi-bin/shop/db.cgi?view=1&id=4724&type=6&path=16x144x8654

I have it on order in Peat's since 2nd December and am losing my patience. It is for a desktop computer that I have. The power supply inside the computer is not standard size so this is my only option.

Maplin only stock upto 300V but I need 500V to be on the safe side. Any help would be most appreciated.

is the PC from the US?

if so most have a switch on the back to change from 120v intput to 240V

is this what your trying to do?

maplin has that exact one

do you need 300W? there's one for 100W and one for 45W aswell

The computer is Japanese. They use 100V over there and the amps are 3.5 so 100 X 3.5 means a minimum of 350V. Japanese electronics for the Japanese market are made with the assumption that there is no world outside Japan so no switches for voltage, etc:p Had problems with my camcorder aswell.
ie.farnell.com look the best because of the free delivery, these things weigh quite a bit. Will go into Peats and get my deposit back at the weekend.

you need 350 Watts, not 350 Volts (power=voltage*current). that thing won't do it because it'll only give 300W. you can get an irish psu instead of a transformer for your current one.

As the last poster said: With a higher voltage it will use less current (as the power will remain constant).

your right about the watts.

but he said earlier that the psu is not a standard size and thats why he can't use an irish one.

having said that, there could be some way to bolt an irish psu to the side of the case ??? might look a bit ****, but what can ya do.

from japan ehe, so not switch, well that sucks

if it is 100V make sure it can take 115-120, as this is what a irish-US transformer will give, normally there is a tolerance and this should be ok. it will be written on the back on the psu.

I tried Maplins Micro PSU but it was the wrong size and shape. You wouldn't believe the tight space the current PSU is wedged into.
The current PSU will operate between 100 and 110 so should be ok. I know people that use their japanese appliances in America and the work ok, just a little bit hotter:D
