220->110 Converter

I have considered going into my various electrical equipment (I am an Electrical Engineer, so test equipment, stereo stuff..) and converting it to 220V. Then I realized that this might be a lot easier if I simply got a big converter. As I searched Amazon, there seemed to be plenty of options, but few if any are actually available. I also noticed most (all?) are using auto-formers.

Does anyone have a recommendation (2kw range)?

Re: 220->110 Converter

First it is 230 V +/- 10% @50 Hz

As you know the transformer will not change the frequency.

> 2000 VA ? Permanent? That is quite a coil you will need.

Re: 220->110 Converter

Thanks,

I will keep the voltage in mind and will be checking it myself during setup.

I will need more than 1kw for sure (derated is 800w) and figure that with overhead 2kw should work. The units I have been looking at use auto-transformers and are therefor considerably lighter (<15kg). Still, I will look for the heaviest one knowing it will have a bigger core and coil. 50Hz is not a problem either as I don't have anything that is using a 60 Hz synchronous motor.

Re: 220->110 Converter

I have a music equipment rental service and we often provide 220/110 transformer sets for visiting bands.
I have 2000VA versions as we are powering large amplifiers but you can buy domestic 500VA versions from Distrelec for example.

Re: 220->110 Converter

I've got one somewhere, either 1500 or 2kW.

I don't need it anymore.

I will look for it.

Yes, audio will be where I need this the most. Though I am now a bit more mature in my music, its not hard for a couple of sub-woofers to suck up this much power alone. This is especially true when the trend is to build smaller sealed box subs that use very long throw woofers that consume prodigious power to achieve deep bass (matching filters to compensate for the roll-off).

Thanks for the offer, I will keep this in mind and maybe we can make a deal. I am told however that shipping via the post is quite high. Its too bad that world events are going the way they are as I otherwise don't mind a little bit of travel.

Re: 220->110 Converter

Wow. That's not high at all. Its a good rate even for 10-30kg package. My wife, who has lived in the US for some time, was surprised as well. I would be happy to work out a price via a PM.
