Description

This Standar specifies general safety requirements for approval and test purposes for ignition transformers for gas and oil burners.

This Standard is an adoption with national modifications and contains the full text of IEC 61558-2-3:1999.

Scope

This International Standard deals with all aspects of safety such as electrical, thermal and mechanical aspects.

This part of AS/NZS 61558 applies to fixed single-phase air-cooled (natural or forced) associated transformers (incorporated or not) used in the ignition system of gas and oil burners, having a rated supply voltage not exceeding 1 000 V a.c. and a rated frequency not exceeding 500 Hz. The rated output current does not exceed 500 mA a.c.

The no-load output voltage and the rated no-load output voltage does not exceed 15,000 V a.c.

This standard applies to transformers where double or reinforced insulation between circuits is not required by the installation rules or by the appliance specification.

This standard is applicable to dry-type transformers. The windings may be encapsulated or non encapsulated.

This standard also applies to transformers incorporating electronic circuits.

This standard does not apply to external circuits and their components intended to be connected to the input and output terminals or socket-outlets of the transformer.
