Dear group, I would like to gather some opinions about safety tests on switch mode power supplies within medical devices, according to IEC 60601-1. My question arises because a test house technician told me he used to test power supplies as they were transformers, for what concerns short circuit and overload tests, on each dc output. I couldn't find such requirements for power supplies in the standard (I couldn't find any!!!), but I think it would be at least wise to do these tests. Do you think they should be included as single fault condition tests, even if not mentioned? Any other thoughts?
