適用范圍：This part of IEC 61558 deals with the safety of bell and chime transformers and powersupply units incorporating bell and chime transformers. Transformers incorporatingelectronic circuits are also covered by this standard.Unless otherwise specified, from here onward, the term transformer covers bell and chimetransformers and power supply units incorporating bell and chime transformers.This part is applicable to stationary, single-phase, air-cooled (natural or forced) independentor associated dry-type transformers. The windings may be encapsulated or nonencapsulated.This standard is applicable to transformers and power supply (linear).This standard used in combination with part 2-16 for switch mode power supply (SMPS) unitsis also applicable to power supplies with internal operating frequencies higher than 500 Hz.Where the two requirements are in conflict, the most severe takes precedence.The rated supply voltage does not exceed 250 V a.c., and the rated supply frequency anddoes not exceed 500 Hz. This standard is applicable to transformers and linear power supplyunits with internal operating frequency not exceeding 500 Hz.The rated output shall not exceed 100 VA.
