This first edition of IEC 61347-2-11, published in conjunction with IEC 61347-1, represents an editorial review of IEC 60920. The formatting into separately published parts provides for ease of future amendments and revisions. Additional requirements will be added as and when a need for them is recognized. This part of IEC 61347 specifies general and safety requirements for miscellaneous electronic circuits used with luminaires for use on a.c. supplies up to 1 000 V at 50 Hz or 60 Hz and/or d.c. supplies up to 250 V. This part does not apply to circuits or devices for which specific IEC standards are published. This first edition of IEC 61347-2-11, together with IEC 61347-1, cancels and replaces the first edition of IEC 60920, published in 1990, and constitutes a minor revision. This standard shall be used in conjunction with IEC 61347-1. The contents of the corrigendum of December 2001 have been included in this copy.
