Lamp controlgear - Part 2-7: Particular requirements for d.c. supplied electronic ballasts for emergency lighting

This part of EN 61347 specifies particular safety requirements for d.c. supplied electronic ballasts for maintained and non-maintained emergency lighting purposes. It includes specific requirements for ballasts and control units for luminaires for emergency lighting as specified by EN 60598-2-22. This first edition of EN 61347-2-7, together with EN 61347-1, cancels and replaces section six of the first edition of EN 60924, published in 1990, and constitutes a minor revision. This standard shall be used in conjunction with EN 61347-1. It was established on the basis of the first edition (2000) of that standard.
