A consumer product is powered by AA cells but also can derive its power from a 
'wall wart' mains-DC PSU via a DC jack input on the product.  The client who is 
the manufacturer of the product (as per the EU directive) has decided to supply 
a third-party wall-wart PSU in the box with the product.  The PSU does not 
carry the product manufacturer's logo but that of the PSU manufacturer (or 
possibly its importer/distributor assuming the responsibility of manufacturer 
because it will inevitably be made in Far East).

Should the product's EU Declaration of Conformity list the LVD directive?  If 
so is it acceptable to list 'LVD only with specific 'manufacturer ABC' 'model 
XYZ' PSU as a clause in the DoC?  I've not ever seen that done but don't see 
why that couldn't be the case.

Should the product's EU Declaration of Conformity also list the 2009/125/EC 
Ecodesign directive in respect of the PSU implementing measures?

Maybe there should be two Declarations of Conformity in the box? One for the 
product and one for the PSU, where the latter is a copy of the PSU 
manufacturer's DoC?

Any thoughts welcome thanks.

Regards all.
