Hi team,

I have one question about surge immunity test of AMC1200 and AMC1100.

on AMC1200 datasheet Viosm is 6kV.

and for AMC1100 Viosm is 4615V. but Vtest is 6kV.

1, these Viosm means same specification? why Vtest =1.3 Viosm?

2. if no, what is the difference?

best regards,
Takuya

Hi Takuya,

they test with a slightly higher voltage to have some safety headroom. They test with 6000Vpk to be able to guarantee safe and proper operation up to 4615Vpk.

Such headroom testing is not unusual.
