Moving From USA Overseas... Looking For Advice re: Electrical Service and Gear

Transformers and autoformers cannot convert frequency. I took a look at the Acupwr devices that were referred to, and I could not find any meaningful information at the site as to how the conversion they provide is accomplished. But it seems to me that there must be some parts and circuitry inside the devices in addition to the "autotransformer" (i.e., autoformer) that is indicated on their label. Which leads me to wonder how pure and undistorted a sine wave the device outputs, if it is in fact a sine wave at all, with that concern heightened by the fact that these devices are described as being intended for use with refrigerators, freezers, and other such appliances.

Before purchasing one of these things I would email the company and ask if they would recommend them for use with a high quality stereo system, and if they can provide some idea of how the frequency conversion is accomplished, and how much distortion is present on the AC output.

Good luck. Regards,

I don't think any of these devices are intended for high quality stereo, that's not the point of making them. They have other transformers that they say don't change frequency just voltage. And I would expect enough distortion on the output. At least they look like quality things compared to cheap Chinese stuff.

+1 on the suggestion to contact the company.

i just pulled out the external transformer connected to my Mom's 27 qf GE fridge, it's by a company outa NY called Todd.
The unit states it's a 3 Prong transformer and converts 50h to 60h as well as 220-240 into 110-120v, 26 years on knock on wood no problems ever with the fridge.

should any of you contact Acupwr, please inform of your findings over here.

Al, why don't you contact them? You will know what they are saying

Done!  I'll post back if and when I receive a response.
