It is a 10vdc Iorn core transformer wall wart 50/60Hz 850mA. Not a
switcher. Most likely it has 4 diodes a fuse and possibly a small cap
insde of it along side the transformer. The regulation is inside of the

You don't understand.

No biggie; apparently you're a newbie. That's OK.

A transformer (and *all* transformers that operate on line
frequency--50/60 Hz--are iron-core, so no need to specify that) converts
AC to AC.

If the wall wart contains diodes, then it's not just a transformer; it's
a DC power supply. (A transformer is part of it.)

So apparently what you have is a DC power supply, judging from the "10
vdc" above.

Not being in the USA at the moment I can't just check it and see

If the supply is rectified and well regulated it will output
10vdc or there abouts.

Having a DC output from a transformer is obviously more common
that you think.

The old style automotive ignition coil (autotransformer)
outputs HV DC.

That's one example, and it is a transformer although not the
kind used for a game system power source, and the output isn't
rectified.

How do you get DC out of a transformer? Must be a really
special one ...

Of course, it's impossible to tell from the O.P. whether the thing in
question is really a transformer (outputs AC) or a
power supply (outputs DC).

To the OP, it would help us to know. What does it say on the
wall wart? Should say something like "10 VAC" or "10 VDC" or
some such.

Lot's of "wall-warts" have a rectifier diode and capacitor in the
same little box. More and more they actually have little
switching regulators in there. Those are more efficient and can
supply much more current, but they usually don't last much more
than about 15 months because they use such crappy little
capacitors in them, and they are virtually unserviceable.

Yes, we know that. My point is that a lot of wall warts are just
what the O.P. called them--transformers--and that we really have no
idea what his is, based on what he posted.

More informations, please.

Come on man... Give me a break.. Technically speaking, yes it is a "Power
Supply" but in it"s absolutely most simple form. I think had I said Power
supply from the beginning I would understand why people would be confused,
with most thinking of a SMPS. It is a transformer with a rectifier. I only
mentioned the 50/60 hz and the mA rating because of all the controversy.

Anyhow, the issue wasn't is it a power supply or not or if it contains
diodes or not....

I'll just check it in a couple of weeks when I'm back home, with my DMM and
see if my guess was right.

It may actually be a bit higher than 12V output, given that for every AC
volt into the rectifier, you will normally get 1.414 DC volts after
rectification and filtering. Regardless, the regulation circuits in the
gaming console should be able to handle the extra voltage quite easily.

Well, that's a power supply. Bare, nekkid, unregulated, but a power
supply nonetheless.

Your guess is probably right.

I'm most intrigued, though, by that "100 V" rating. Is that written on
the outside? Because that's a nonstandard voltage, at least for the
parts of the world I'm familiar with. Where are you? What's the line
voltage where you live?

Maybe it's just a "nominal" rating, like the 90-140 V or so that some
power supplies will handle. In any case, the advice that others have
given here, basically "don't sweat it, the device's regulation will take
care of things" is good.

100V is a standard voltage in Japan. What's really interesting about Japan
is that they not only use 100/220V power, but also 50 AND 60 Hz line
frequencies.

Butbutbut ... shouldn't that be 100/200 V? Usually the higher voltage is
double the lower one (two equal legs of the lower voltage). Here in
North American it's actually 120 & 240, at least nominally.

Sorry I tuned in late, 100V is the standard line voltage in Japan.

I can't say what will happen to the device but it is an unregulated supply
it will put out 12 volts instead of 10, and get hot.

** Read the whole thread - imbecile.

Because Japan uses 50 Hz, the tranny will not run any hotter at 120 volts
at 60 Hz.


If that will damage the supply, or the device is hard to guess.

** Guessing is always easy - imbecile.



What I suggest to people who move here (Israel) from the US is to take the
supply to a good electronics store and they will sell you a replacememnt
that has the correct voltage, current supply and connector.

** Japan uses the same AC sockets as the USA.

There is simply no issue.

If that is not possible, and you can't get a local electronics person to
fit a proper supply (for example if the connector is unusual), then you
may want to go to a transformer manufacturer and make up a 120->100 volt
transformer. My guess is that a small one will cost $50-$75.

Here they are stock items (230-100) because due to the different power factor
(50Hz vs 60Hz line frequencyt) large motorized 120 volt appliances last longer
on 100v than 120.

You are correct! In Tokyo and East Japan it is 100V 50Hz. In Osaka and West
Japan it is 100V 60Hz. Some appliances wont work in both reigions, but those
are mostly older. Things using mechanical timers (a bit rare these days in
Japan everything is digital now) always have a 50/60Hz switch.
