Can I rely on my power supply’s CE report to claim my final product is CE compliant?

No. A power supply’s CE report only covers the power supply as a standalone component under its own test configuration. It does not automatically confer CE compliance on the finished product. In the final product, the power supply interacts with various loads, grounding, cable configurations, enclosures, and operating modes, which can materially affect conducted and radiated emissions and immunity behavior. You can reference the power supply’s safety documentation as part of your technical file, but EMC and safety compliance must be demonstrated at the final product level. The CE mark applies to the finished apparatus placed on the EU market, not to individual components in isolation.
