Safety of power transformers, power supply units and similar devices - Part 2-12: Particular requirements for constant voltage transformers

Apstrakt

This part 2 of IEC 61558 is intended to be used in conjunction with IEC 61558-1.


This international standard deals with all aspects of safety such as electrical, thermal and mechanical.

This part of IEC 61558 applies to stationary or portable, single-phase or polyphase, air-cooled (natural or forced), associated or independent:


- constant voltage auto-transformers;
- constant voltage separating transformers;
- constant voltage isolating transformers;
- constant voltage safety isolating transformers;


having a rated supply voltage not exceeding 1 000 V a.c., a rated frequency not exceeding 500 Hz, an internal operational frequency not exceeding 30 kHz and no limitation of the rated output.


It has the status of a group safety publication in accordance with IEC Guide 104
