Specifies general safety requirements for approval and test purposes for shaver transformers. This Standard is an adoption with national modifications and contains the full text of IEC 61558-2-5:1997.
Replacement:
This part 2-5 of IEC 61558 applies to shaver supply units, embodying one or more socket-outlets and a single phase air cooled isolating transformer, having a rated supply voltage not exceeding 250 V a.c., a rated output not less than 20 VA and not exceeding 50 VA, a rated output voltage not exceeding 250 V, and a rated frequency not exceeding 500 Hz.
This standard is also applicable to shaver transformers for embodiment into shaver supply units.
NOTE 1 Shaver supply units may be flush or surface mounted or incorporated in luminaires and other equipment. NOTE 2 Shaver supply units may be used to supply shavers, tooth brushes and similar small power devices.
This part 2-5 of IEC 61558 applies to shaver transformers for embodiment into shaver supply units. These transformers are single phase air cooled isolating transformers, having a rated supply voltage not exceeding 250 V a.c., a rated output not less than 20 VA and not exceeding 50 VA, a rated output voltage not exceeding 250 V, and a rated frequency not exceeding 500 Hz.
NOTE 301 Requirements for shaver supply units are contained in AS/NZS 3194.
