Title: Help ! 220V to 110V power supply switch?
Post by: ckillerh3 on December 26, 2005, 09:36:28 PM
Hi -

I bought an Amiga 1200 in an Infinitiv II tower
from EBay.de.  I think the Infinitiv was made
by Micronik? Anyway this unit naturally was  running
220V 60Hz power.  

Every computer power supply I've ever seen has a
switch on the back to switch from 220V 60Hz to 110V 50Hz.
I'm getting cold feet - I just don't want to flick the
switch and blow out the new computer just <>
this will be OK.  Has anybody got any experience with
these power supply units and switching from different
operating currents !

Stephen

if it has the switch, and it is set to 110 and you have the correct cable to your outlet, everything should be fine. i dont have that setup, but they probably got a standard 3rd party psu unit, added their own cable to the 1200, and installed that into their case.

I think you might have your Hz the wrong way round!

220-240V, 50Hz = most of the world
110V, 60Hz = US/Japan

Yup - it "hurts" that USA has the less efficient power source. Thanks for clarification 50 Hurts vs 60 Hurts. I had it backwards.

<< 220-240V, 50Hz = most of the world
110V, 60Hz = US/Japan >>

japan is actually 100V, but 110 stuff works fine here usually.

just switch it to corresponding voltage and it will works
forget teh freq. problem .)
I have couple of US/japan consoles and computers and it works like charm, only with own handmade 240>120 stepdown transformator

@countzero - thanks for the Wikipedia link - quite odd how the world uses so many different mains sockets...

Must be a bit dodgy for power in Afghanistan - "Voltage may vary from 160 to 280."  :-o

That'd be bye bye Amiga PSU, I think!!!
