DIN EN IEC 61347-2-2:2025-06

This document specifies safety requirements for electronic step-down convertors for use on DC supplies of up to 1 500 V or AC supplies of up to 1 000 V at 50 Hz or 60 Hz, and with a rated output voltage ≤ 50 V (RMS) at a frequency deviating from the supply frequency, or 120 V ripple free DC between conductors and between any conductor and earth, associated with tungsten-halogen lamps as specified in IEC 60357, and other filament lamps. There are no restrictions on the scope of this document. The standard differs from DIN EN 61347-2-2 (VDE 0712-32):2012-11 as follows: - introduction of dated references to the fourth edition of IEC 61347-1 as appropriate; - deletion of the clauses and subclauses which are either no longer relevant or now covered in IEC 61347-1; b) scope extension to 1 500 V for direct current; c) scope clarification; d) deletion of unused definitions; e) revision of information and marking requirements; f) revision of compliance conditions for the measurement of the output voltage during fault condition testing and during thermal testing. This document specifies safety requirements for filament lamp equipment. Typical examples include electronic converters that supply voltage to tungsten-halogen lamps or other filament lamps.
