Hi Hangjie,

Thanks for your questions.

As you have already pointed out, the main reason we test 1.2xVISO is the UL1577 standard. I have reached out to an expert regarding why this is the case. Please allow us some additional time to provide an answer.

Hi Hangjie,

As you pointed out from the UL 1577 standard, we test 100% of the devices in production with 1.2 x VISO AC RMS voltage (60 Hz frequency). I hope this clarifies the confusion.

Thanks,
Saleem
