Controlgear for electric light sources - Safety - Part 2-2: Particular requirements - Electronic step-down convertors for filament lamps


IEC 61347-2-2:2024 specifies safety requirements for electronic step-down convertors for use on DC supplies of up to 1 500 V or AC supplies of up to 1 000 V at 50 Hz or 60 Hz, and with a rated output voltage = 50 V (RMS) at a frequency deviating from the supply frequency, or 120 V ripple free DC between conductors and between any conductor and earth, associated with tungsten-halogen lamps as specified in IEC 60357, and other filament lamps.

This third edition cancels and replaces the second edition published in 2011. This edition constitutes a technical revision.

This edition includes the following significant technical changes with respect to the previous edition:

a) alignment with respect to the fourth edition of IEC 61347-1;

- deletion of the clauses and subclauses which are either no longer relevant or now covered in IEC 61347-1;

b) scope extension to 1 500 V for direct current;

c) scope clarification;

d) deletion of unused definitions;

e) revision of information and marking requirements;

f) revision of compliance conditions for the measurement of the output voltage during fault condition testing and during thermal testing.
