Safety of transformers, reactors, power supply units and similar products for supply voltages up to 1100 V. Part 2-13: Particular requirements and tests for auto transformers and power supply units incorporating auto transformers

SKU: *SLNS/BS EN 61558 – 2 - 13: 2009 Category:

This part of IEC 61558 deals with the safety of auto transformers for general applications
and power supply units incorporating auto transformers for general applications.
Transformers incorporating electronic circuits are also covered by this standard.
NOTE 1 Safety includes electrical, thermal and mechanical aspects.
Unless otherwise specified, from here onward, the term transformer covers auto
transformers for general applications and power supply units incorporating auto
transformers for general applications.
NOTE 2 : For power supply units (linear) this part is applicable. For switch mode power supply units, IEC 61558-2-16 is
applicable together with this part.
This part is applicable to stationary or portable, single-phase or polyphase, air-cooled
(natural or forced) independent or associated dry- type transformers. The windings may be
encapsulated or non-encapsulated.
The rated supply voltage does not exceed 1 100 V a.c., and the rated supply frequency
and the internal operating frequencies do not exceed 500 Hz.
