using 110V receiver with 220V converter

[gamb00ler]

I'm moving to Hang Dong later this year.  I'm trying to sell all our 110V goods.  I'm thinking about keeping an Onkyo home theatre receiver because it doesn't seem that I will get much selling it.  Would this function OK if I use it with a 220V to 110V converter?

What type of 110V equipment is not suitable for running on a converter?

 

I'm shipping a 20' container so weight or space isn't an issue.

 

Thanks

Most all receivers I have owned over the past 40 years or so have a switch on the back for 110-220V.  If so you're good.  Otherwise, a 220 to 110 volt converter should be OK as the 50 Hz shouldn't be an issue.

 

Almost anything with a motor will have issues with the frequency difference.

Transformer only converts the voltage - if not rated 50-60Hz there could be issues.  For motors they would run slow.  For transformers they could overheat as 60Hz is cheaper to make so equipment made only for 60Hz take advantage of that.

Actually a lot of stuff sold in USA is not rated 110-220v or even 50-60Hz as the market is huge and the few cents saved is worth making a different model for that market.

I'm from the states and there's lot's of products with a 110-220V switch on the back or just takes it.  Cheers.

My receiver is ONLY 110-120V

Don't bring anything with an inductive load, ie. anything with a motor like fans and fridges since the 50 Hz AC here will make for huge inefficiencies regardless of step-sown voltage converters.

Generally, running 60Hz appliances on 50Hz is a bit of a lottery. Many people have been running kit via transformers with no issues whatever, others have had rather less success.

 

In this instance the issue will be with the transformer, 60Hz transformers can get away with less iron than those designed for 50Hz and may saturate and overheat on 50Hz.

 

If it has a 220v switch and the rating plate says 50/60Hz you're good to go.

 

Pop the lid, the transformer may have 220V windings anyway, a simple re-wiring job.

 

Onkyo are a well known global brand, your local electronics chap should be able to source a 220V 50Hz part for it. 

 

If you can get a Japanese (100V) converter it will likely work just fine and be good forever on 50Hz.

 

Is it worth the time and effort? UP2U.

Does it make a difference that half of Japan is on 50Hz while the other half is on 60Hz? Pretty messed up isn't it?
