EN 61558-2-6

Safety of transformers, reactors, power supply units and similar products for supply voltages up to 1 100 V
Part 2-6: Particular requirements and tests for safety isolating transformers and power supply units incorporating safety isolating transformers

ANNEE FILE EDITION SCAME
1997 N127
       

European Standard

 

Sommaire
(courtoisie CENELEC)

This part 2 of IEC 61558 applies to stationary or portable, single-phase or polyphase, aircooled safety isolating transformers, associated or otherwise, having a rated supply voltage not exceeding 1000 V a.c. and rated frequency not exceeding 500 Hz, the rated output not exceeding:
– 10 kVA for single-phase transformers;
– 16 kVA for polyphase transformers.

This standard is also applicable to safety isolating transformers without limitation of the rated output; however such transformers are considered as special transformers and are subjected to an agreement between the purchaser and the supplier.

The no-load output voltage and the rated output voltage does not exceed:
50 V a.c. r.m.s. and/or
120 V ripple-free d.c.
between conductors or between any conductor and earth.

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