Hello Luiz, When it comes to voltage ranges you are not going to get accurate information from any source other than the power utilities in those countries. However, depending on the power distribution network within a country the voltage ranges can be different from one municipality to another. The best way to address this issue is to determine what voltage tolerances you want to design into your product based on established nominal voltages around the world. Depending on how robust you want to make your product you may want to have a large tolerance range, say +/- 10% and type test your products to +/- 12%. Also, depending on your concern for safety versus performance, you may specify a tolerance range of +/- 5% and verify that if the voltage goes out of this range that the product remains safe even though its performance may be degraded. Another alternative is to specify a controlled voltage environment for your product. Regards, +=================================================================+ |Ronald R.

Dear Colleagues, I am trying to find reliable information regarding the actual voltage range found in some Asian countries. I already have some information, but it looks like the actual conditions are worse than those published. Since travelling to each country with a multimeter would be quite expensive, I would really appreciate if someone could give me some help. Specifically, I am looking for information about the following countries: Taiwan Thailand Philippines Hong Kong Singapore India Malaysia South Korea Thanks in advance for your kind attention. Regards, Luiz
