Re: [PSES] PSU cert issue

2024-03-22 Thread Jim Bacher, WB8VSU 
Jeff, all of the power supply modules I have dealt with had EMC Reports. 
Those modules went inside products. So I would have required the PSU to 
have a vendors EMC report before accepting its use in one of our products.


The suppliers I dealt with used 3 different resistive loads, during their 
testing. One minimal load, one mid load and one max load. The resistors 
where typically bolted to an aluminum sheet for heat dissipation.


One of the reasons you want them to test is for line conducted levels. 
Those levels are usually impacted by load. There is likely nothing you can 
do in your product, to correct the power supplies if they failed line 
conducted.


Turkey was always difficult for me. I had to on numerous occasions explain 
how to interpret the European requirements.  I would provide a copy of your 
products EMC report, highlighting the power supply was part of the test, 
and therefore a valid EMC report for the power supply.

Re: [PSES] PSU cert issue

2024-03-22 Thread Gert Gremmen F4LDP 

Formally they (customs) are right.
PSU's are equipment in their own right just as PC plug-in cards and need 
EMC (CE) marking.
Testing in a full system does not guarantee that the result is the same 
as in another system, especially not in PC world where parts change 
quicker than transport time.


I do not understand why LVD and ROHS would be taken care of and not EMC.
Wasn't the electrical safety tested as part of a full system  ? 
Not the first time that customs in a associated country (for CE) are 
more severe as the EU itself. I've seen before.
It's all part of the making sure they are fit for an EU membership (even 
if local politics dare/won't not say the "join" word yet)

Dear Gilbert,

One Soulution could be:
You have to include the whole list of all separate orderable spare 
part modules to your CE Declaration.

Of course the PSU is EMC LVD etc. tested in the overall system.
Also be aware that Turkey checks the Date of Issue of your CE 
Declaration against the Date of arrival of your goods in Turkey and 
therefore whether or not you had a valid CE Declaration at the time of 
importing your spare part.
