Description

This Standard specifies general safety requirements for approval and test purposes for transformers for switch mode power supplies.

This part of AS/NZS 61558 applies to associated power transformers for switch mode power supplies, single-phase or polyphase, air-cooled: separating transformers; isolating transformers; safety isolating transformers, having a rated supply voltage not exceeding 1000 V a.c. and a rated frequency of 500 Hz to 1 MHz, the rated output not exceeding:

• 10 kVA for single-phase transformers;
• 16 kVA for polyphase transformers.

Scope

This Standard does not include the text of IEC 61558.2.16 Ed.1 which provides manufacturers, designers, regulatory authorities, testing laboratories and similar organizations with safety requirements for the design, manufacture and testing of switch mode power supply units and transformers for switch mode power supply units which can form the basis for approval by regulatory authorities.

Adopted from IEC 61558.2.16 Ed.1.
