IEC 61347-2-3:2011 specifies particular safety requirements for electronic control gear for use on a.c. and d.c. supplies up to 1 000 V at 50 Hz or 60 Hz with operating frequencies deviating from the supply frequency, associated with fluorescent lamps as specified in IEC 60081 and IEC 60901, and other fluorescent lamps for high-frequency operation. This second edition cancels and replaces the first edition published in 2000, its Amendment 1 (2004) and its Amendment 2 (2006), IEC 61347-2-4 published in 2000, IEC 61347-2-5 published in 2000 and IEC 61347-2-6 published in 2000. This second edition constitutes a technical revision. The significant revisions with respect to the first edition are: - rectifying test conditions when dimming; - construction requirements; - measurement circuits and limits for HF leakage currents; - modification of the structure to become a standard exclusively for a.c. and d.c. central supplied electronic control gear for general lighting and Annex J cover centrally- supplied emergency control gear. This publication is to be read in conjunction with IEC 61347-1:2007. The contents of the corrigendum of September 2011 have been included in this copy.
