Description
This Standard specifies general safety requirements for approval and test purposes for transformers for switch mode power supplies.
This Standard is an adoption with national modifications and contains the full text of IEC 61558-2-17:1997.
Scope
This part 2 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.
The no-load output voltage or the rated output voltage do not exceed:
- 1000 V a.c. or 1 415 V ripple-free d.c for separating transformers;
- 500 V a.c. or 708 V ripple-free d.c for isolating transformers.
- 50 V a.c. r.m.s. and/or 120 V ripple-free d.c for safety isolating transformers.
This standard is applicable to dry type transformers. The windings may be encapsulated or non-encapsulated.
