Lamp controlgear - Part 2-4: Particular requirements for d.c. supplied electronic ballasts for general lighting

This part of EN 61347 specifies particular safety requirements for d.c. supplied electronic ballasts intended for operation from transient and surge-free power sources, operated directly from batteries without charging equipment as used in leisure equipment, for example, caravans, etc. This first edition of EN 61347-2-4, together with EN 61347-1, cancels and replaces section three 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.
