This part of IEC 61347 specifies safety requirements for electronic step-down convertors for use on DC supplies of up to 1 500 V or AC supplies of up to 1 000 V at 50 Hz or 60 Hz, and with a rated output voltage ≤ 50 V (RMS) at a frequency deviating from the supply frequency, or 120 V ripple free DC between conductors and between any conductor and earth, associated with tungsten-halogen lamps as specified in IEC 60357, and other filament lamps.

NOTE 1 The limits of 50 V (alternating current) and 120 V (direct current) are in accordance with the extra-low-voltage (ELV) band of IEC 61140:2016.

NOTE 2 Performance requirements are covered by IEC 61047.

NOTE 3 Such step-down convertors can also be used for electric sources producing optical radiation with the same technology used for purposes different than illumination and producing radiation other than visible spectrum.
