AS/NZS 61558.2.8:2025 deals with the safety of bell and chime transformers and power supply units incorporating bell and chime transformers.
This Standard will supersede AS/NZS 61558.2.8:2011 three years from the date of publication (i.e. on 27 June 2028). During this period, it is anticipated that regulatory authorities will approve transformers and power supply units for bells and chimes to either standard.
