Hello group,
For years I have used off-the-shelf and custom EMI filters with a fully
enclosed metal canister. Why is this enclosure required? Are there
specific provisions in the standards? My idea is to build up the filter
circuit on a printed circuit board and make it an integral part of the
power supply.
I am currently looking at EN133200 which has certain seal tests but after
reviewing these, they all appear to be related to climatic or environmental
conditions. If the product passes these tests without the enclosure it
would seem that the product has passed, period.
Alternatively I have considered removing the nomenclature "EMI filter" and
simply call it an input module, then evaluate it as a part of the overall
system. If it passes the EMC and Product Safety requirements, can I call
the job complete?
Any thoughts?
