Describes the electronic step-down convertors for use on d.c. supplies of up to 250 V or a.c. supplies of up to 1000 V, at 50 Hz or 60 Hz and with rated output voltage <= 50 V r.m.s. at a frequency deviating from the supply frequency, or 120 V ripple free d.c. between conductors and between any conductor and earth, associated with tungsten-halogen lamps as specified in IEC 60357 and other filament lamps.
