For Mexico NOM mark, it is 127Vac, Hi-Pot (Electric Strenth Test)can follow related IEC standards, such as IEC 60950-1 if your adapter is for ITE use. Pri to Ground use AC 3000V/1 min, Pri to Sec use AC1500V/1 min.

謝謝您!但是我有聽講nom-001標準與iec60950-1標準不一樣,不知此情況是否正確.

Hi Angel, Mexico just join CB member since this year. Basically NOM-001-SCFI-1993 is following IEC standards requirements without any problem.

了解,墨西哥是CB成員國.我司送樣的樣品是用60950去預測的,只是後來有個工程師跟我講與IEC標準不一樣.感覺奇怪.謝謝您的回復...

Pri to Gound use AC3000V/1min, Pri to Sec use AC1500V/1min??????????

It should be Pri to Gound use AC1500V/1min, Pri to Sec use AC3000V/1min.

You are correct, sorry for my typing error!

i/p: 120V OR 127V, Pri. to Ground是Basic insulation, Hi-Po 1000Vac/1min, Pri. to Sec. 2000Vac, 若Transformer初次级之间工作电压有过184Vac, 则为3000Vac,此时应断开地线测.
若工作电压大于354V, 则需查IEC60950-1,Tabel5B, part2确定.

哇!怎麼答案這麼多,我都不知道哪一种是對的了.
