Within our organization we have some discussion wrt rated input power.
Approach A:
Sum up all the maximum power of the supplies that are in the MEE. This is about 200W.
Rationale: IEC60601-1 3ed Clause 4.11 last sentence: A supplier certification may be used in place of the above measurement as the basis for steady state current or input power specification.
Approach B:
Measure the input power (for 100/240Vac 50/60Hz) and either use single value or a range?
And include some realistic design margin (eg 5%) This is about 80W.
Rationale: IEC60601-1 3ed Clause 4.11: The steady state MEASURED input of the MEE or MES at RATED voltage.
The result in both approaches is imho too big 200W vs 80W.
I think that rated value on the marking should make sense and therefor e not be too much over rated?
What do you prefer?
