I am wondering how easy it will be to get this product idea to pass EMC?

it is a LED Driver for 40 Watts.
Input voltage is Car Battery (13.5V)

All the modules used are pre-conformant to pass EMC , but i do not know whether this idea will pass EMC because it uses 6 modules in the one product, as you can see.

the Modules used are RCD-24-1.2 .......

and the RPP30-2415DW

You see , all the Power Modules used here conform to EMC regulation EN55022, Class B .

But my question is......will the above product (which uses 6 of these modules) still conform to EN55022, Class B ?

- Strictly spoken, the RCD-24 datasheet requests an input filter for EN55022 conformance
- Apart from this, EMC regulations have to be kept by devices rather than components. A manufacturer can at best
estimate EMC properties for typical usage of the component/module.

A critical point with isolated DC/DC converters is the interference current injected between primary and secondary ground.
It's EMC effect strongly depend on the external circuit details.
