Angol cím

Safety of transformers, reactors, power supply units and combinations thereof. Part 2-5: Particular requirements and tests for transformers for shavers, power supply units for shavers and shaver supply units (IEC 61558-2-5:2024)

Alkalmazási terület

Replacement: This part of IEC 61558 deals with the safety of shaver transformers, power supply units incorporating a shaver transformer, and shaver supply units. Shaver transformers incorporating electronic circuits are also covered by this document. NOTE 1 Safety includes electrical, thermal and mechanical aspects. Unless otherwise specified, from here onward, the term transformer covers shaver transformers and power supply units incorporating shaver transformers and shaver supply units. For power supply units (linear) this document is applicable. For switch mode power supply units IEC 61558-2-16 is applicable together with this document. Where two requirements are in conflict, the most severe take precedence. This document is applicable to stationary, single-phase, air-cooled (natural or forced) independent or associated dry-type transformers. The windings can be encapsulated or nonencapsulated. The rated supply voltage does not exceed 250 V AC and the rated supply frequency and the internal operating frequencies do not exceed 500 Hz. The rated output is not less than 20 VA and does not exceed 50 VA. The no-load output voltage does not exceed 275 V AC and the rated output voltage does not exceed 250 V AC. This document is not applicable to external circuits and their components intended to be connected to the input and output terminals or socket-outlets of the transformers. NOTE 2 Transformers covered by this document are only used in applications where double or reinforced insulation between circuits is specified by the installation rules for bathrooms and similar locations, or by the appliance specifications. NOTE 3 Transformers covered by this document can be flush or surface mounted or incorporated in luminaires, mirrors, and other equipment containing one or more socket-outlet(s). Attention is drawn to the following, if applicable: – for transformers intended to be used in vehicles, on board ships, and aircraft, additional requirements (from other applicable standards, national rules, etc.); – measures to protect the enclosure and the components inside the enclosure against external influences such as fungus, vermin, termites, solar-radiation, and icing; – the different conditions for transportation, storage, and operation of the transformers; – additional requirements in accordance with other appropriate standards and national rules can be applicable to transformers intended for use in special environments. Future technological development of transformers can necessitate a need to increase the upper limit of the frequencies. Until then this document can be used as a guidance document. This group safety publication focusing on safety guidance is primarily intended to be used as a product safety standard for the products mentioned in the scope but is also intended to be used by technical committees in the preparation of publications for products similar to those mentioned in the scope of this group safety publication, in accordance with the principles laid down in IEC Guide 104 and lSO/lEC Guide 51. One of the responsibilities of a technical committee is, wherever applicable, to make use of basic safety publications and/or group safety publications in the preparation of its publications.
