Annotation of standard text IEC 61347-2-2-ed.3.0 :
IEC 61347-2-2:2024 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. This third edition cancels and replaces the second edition published in 2011. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) alignment with respect to the fourth edition of IEC 61347-1; - 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. LIEC 61347-2-2:2024 specifie les exigences de securite applicables aux convertisseurs abaisseurs electroniques destines a etre utilises sur des alimentations en courant continu jusqua 1 500 V ou sur des alimentations en courant alternatif jusqua 1 000 V a 50 Hz ou 60 Hz et de tension de sortie assignee <= 50 V (en valeur efficace) a une frequence differente de celle de la tension dalimentation, ou 120 V en courant continu lisse entre conducteurs et entre un conducteur et la terre, associes a des lampes tungstene-halogene, comme cela est specifie dans lIEC 60357, et dautres lampes a incandescence. Cette troisieme edition annule et remplace la deuxieme edition parue en 2011. Cette edition constitue une revision technique. Cette edition inclut les modifications techniques majeures suivantes par rapport a ledition precedente: a) alignement sur la quatrieme edition de lIEC 61347-1; - ajout de references datees a la quatrieme edition de lIEC 61347-1, le cas echeant; - suppression des articles et paragraphes qui ne sont plus pertinents ou qui sont desormais couverts dans lIEC 61347-1; b) extension du domaine dapplication a 1 500 V pour le courant continu; c) clarification du domaine dapplication; d) suppression des definitions non utilisees; e) revision des exigences relatives aux informations et aux marquages; f) revision des conditions de conformite pour le mesurage de la tension de sortie lors des essais en conditions de defaut et lors des essais thermiques.
