Standards for Transformers (Power Supplies)

Standards cover electrical safety, installation energy efficiency and electromagnetic compatibility standards for different types of transformers. Low voltage transformers are also required to meet ingress (IP) protection tests.

Australian and New Zealand standards

  • AS/NZS 4417.2:2009 Marking of electrical and electronic products to indicate compliance with regulations - Specific requirements for electrical safety regulatory applications
  • AS/NZS 3820:2009 Essential safety requirements for electrical equipment
  • AS/NZS 61558 series including:
  • AS/NZS 61558.1:2008 Safety of Power Transformers, Power Supplies, Reactors and Similar Products - General requirements and tests
  • AS/NZS 60950.1:2003 Information technology equipment - Safety - General requirements
  • AS/NZS 3000:2007 Electrical installations (the ‘Australian/New Zealand Wiring Rules’)
  • AS/NZS CISPR 14.1:2010 Electromagnetic Compatibility - Requirements for household appliances, electrical tools and similar apparatus – Emission
  • AS/NZS CISPR 14.2:2003 Electromagnetic compatibility - Requirements for household appliances, electric tools - Immunity - Product family standard
  • AS/NZS CISPR 22:2009 Information technology equipment - Radio disturbance characteristics - Limits and methods of measurement
  • AS/NZS 4665 series: Performance of external power supplies
  • AS/NZS 4879 series: Performance of transformers and electronic step-down convertors for ELV lamps
  • AS/NZS 4251 series: Electromagnetic compatibility (EMC)
  • AS/NZS 61000 series: AS/NZS 61000 Electromagnetic compatibility (EMC)
  • AS/NZS 61558 series: Safety of Power Transformers, Power Supplies, Reactors and Similar Products

Other regulations

  • The Australian Communications and Media Authority (ACMA) may still regulate AS/NZS CISPR 14.1:2003 Electromagnetic Compatibility - Requirements for household appliances, electrical tools and similar apparatus – Emission.  This standard has been superseded by the 2010 edition.
  • European Directive 2005/32/EC of the European Parliament and of the Council of 6 July 2005 (the ‘Energy Using Products (EuP) directive').  Manufacturers of imported electrical equipment may have completed CE certificates to this directive.
