Approvals and compliance

From the manufacturer's datasheet for this series

United States

  • UL

    UL Listing or Recognition means UL Solutions tested samples against the applicable UL safety standard and audits the factory that builds them. A UL file number is the usual evidence an inspector or specifier asks for in North America.

    Covers only part of this series: for 12V,24V only

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

  • ENEC

    ENEC is a pan-European mark for electrical equipment, issued by a national certification body and recognised across the member schemes. It covers both product testing and factory surveillance, which is what separates it from a self-declared CE mark.

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.

An approval above is held by only some models in this series. The datasheet's own wording is quoted beside the mark; read it against this part number, and ask us for the certificate if your approval process needs it.

Isolation and electromagnetic compatibility
Withstand voltage I/P-O/P:3.75KVAC

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.
