Approvals and compliance

From the manufacturer's datasheet for this series

Canada

  • CSA

    Certification to a CSA C22.2 standard, the Canadian counterpart of the UL series. Datasheets cite the specific C22.2 number, which is how you tell a power-supply certificate from a luminaire-controlgear one.

Europe

  • TÜV

    A TÜV certificate is third-party testing against the European EN standard. It is the evidence behind a CE declaration rather than a replacement for it: CE remains the manufacturer's own declaration, and the TÜV report is what makes that declaration defensible.

Eurasian Economic Union

  • EAC

    Conformity with the Eurasian Economic Union technical regulations, covering Russia, Belarus, Kazakhstan, Armenia and Kyrgyzstan. TP TC 004 is the low-voltage regulation and TP TC 020 the electromagnetic-compatibility one, so which number appears tells you what was assessed.

  • EN 60601-1
  • IEC 60601-1

Designed to reference

The datasheet lists these as design references. The series was built to them but has not been certified to them, so do not treat them as approvals.
