This part of IEC 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 IEC 61347-2-4, together with IEC 61347-1, cancels and replaces section three of the first edition of IEC 60924, published in 1990, and constitutes a minor revision.This standard shall be used in conjunction with IEC 61347-1. It was established on the basis of the first edition (2000) of that standard.
