How to connect a 120V device to Australian mains supply?

[Arno]

Hi,

I have very little knowledge of electronics and I think this is a
fairly basic question. I have a Sangean WR-2 radio bought in the US
that I want to use in Australia. The radio is powered 120V/60Hz/24W.
In Australia we have 240V at 50Hz.

What do I need to do to use this device safely in Australia, apart
from buying the plug adapter?

Regards,

Arno

** Go to Dick Smith Electronics and buy a step down transformer.

Gosh, is DSE still alive over there? Thay made a big push into the US
some years back, lots of catalogs and ads. They opened a store in
Mountain View, pretty deep into Silicon Valley, but it was in a bad
location and had fairly dinky stuff, and it couldn't compete. Too bad,
he had some interesting stuff and his catalogs were fun.

This is the cheapest oscilloscope I've ever seen:

You need a transformer with the the proper adabtors to step down the
AC mains to 120 VAC for the radio.

** All 240/120 step-down transformers sold in Australia have them.

There may be an issue with the line
frequency for some products. Many North American devices are 60 Hz
only.

** Sangean radios are made in Asia - where 50 Hz operation is the norm.

When used with 50 Hz their power supply may run on the warm
side. If there are any circuits that are mains frequency depended,
then these circuits will be working out of specs.

** The built in clock may be way out.

Yeah, that's the one. Web sites used to have pages that you could
actually bookmark and link to. I guess too many people were buying too
much stuff, and they had to stop that.
