1 Scope
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 [A1_start]1 000[A1_end] V at 50 Hz or 60 Hz and/or d.c. supplies up to 250 1 000 V. This part [A1_start]of IEC 61347[A1_end] does not apply to circuits or devices for which specific IEC standards are published.
NOTE Examples of miscellaneous electronic circuits used with luminaires are
-
— electronic ballast control circuits;
-
— switching circuits used in association with daylight and/or presence sensors;
-
— circuits to assist EMC performance;
-
— intermittence and similar devices used with lighting chains;
-
— earth leakage or open-circuit protective devices used with neon transformers.
