Ok ,thank you very much. Again, I was asking for an opinion concerning the expediency of doing some tests not explicitly required by the medical device standard, when you have to cope with a power supply not previously tested at all.
It's not a matter of SMPS theory, but it seems that someone's skill in answering my original question is not as good as his arrogance.
