Anotation

IEC 61558-2-12:2024 deals with the safety of constant voltage transformers for general applications and power supply units for constant voltage for general applications. Constant voltage transformers incorporating electronic circuits are also covered by this document. 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) adjustment of structure and references in accordance with IEC 61558-1:2017; b) description of constructions moved to IEC 61558-1:2017; c) new symbol for power supply unit with linearly regulated output voltage. It has the status of a group safety publication in accordance with IEC Guide 104. LIEC 61558-2-12:2024 traite de la securite des transformateurs a tension constante pour applications dordre general et des blocs dalimentation pour tension constante pour applications dordre general. Les transformateurs a tension constante qui incorporent des circuits electroniques sont egalement couverts par le present document. 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) la structure et les references ont ete alignees sur l’IEC 61558-1:2017; b) la description des constructions a ete deplacee dans l’IEC 61558-1:2017; c) un nouveau symbole a ete ajoute pour les blocs dalimentation dont la regulation de la tension secondaire est lineaire. Il a le statut de publication groupee de securite conformement au Guide 104 de lIEC.
