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.

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.

Isolation and electromagnetic compatibility
Withstand voltage I/P-O/P:4KVAC

Standards certified against

  • ANSI/AAMI ES60601-1
  • IEC 60601-1
  • IEC 60601-1-11
