Scope

Replacement: This part of IEC61558 deals with safety aspects of transformers for toys and pow supplies incorporating transformers for toys such as electrical, thermal and mechanical safety. This Part 2-7 is applicable to transformers for toys and pow supplies incorporating both transformers for toys and electronic circuits. This Part 2-7 is not applicable to external circuits and their components intended to be connected to the input terminals, output terminals or socket-outlets of the transformers and pow supplies. This Part 2-7 applies to stationary and portable, single-phase, air-cooled (natural or forced), transformers for toys and pow supplies incorporating transformers for toys, having a rated supply voltage not exceeding 250 V a.c., a rated supply and internal operating frequency not exceeding 500 Hz, a rated output not exceeding 200 VA and a rated output current not exceeding 10 A. This Part 2-7 is applicable to independent transformers and transformers for specific use. This Part 2-7 is applicable to dry-type transformers for toys. The windings may be encapsulated or non-encapsulated. The no-load output voltage does not exceed 33 V a.c. for transformers for toys and pow supplies incorporating transformers for toys, or 46 V ripple-free d.c. for pow supplies incorporating transformers for toys, and the rated output voltage does not exceed 24 V a.c. for transformers and pow supplies , or 33 V ripple-free d.c. for pow supplies . In general, this Part 2-7 does not take into consideration children playing with the transformers for toys and pow supplies incorporating transformers for toys.
