1 Scope

This document specifies special safety requirements for electronic step-down converters for tungsten halogen lamps and other tungsten filament lamps described in IEC 60357: This kind of the electronic buck converter uses a DC power supply not greater than 250V or an AC power supply not greater than 1000V with a frequency of 50Hz or 60Hz:

source, its rated output voltage between conductors or between any conductor and the ground is not greater than 50V (effective value), and its operating frequency is different from that of the power source:

source frequency, or no more than 120V ripple-free DC voltage:

Note: The 50V rated output voltage limit meets the requirements of voltage section I in GB/T 18379-2001:

Special requirements for electronic buck converters equipped with overtemperature protection are given in Appendix C:

Special supplementary requirements for safety extra low voltage (SELV) converters are given in Appendix I:

Performance requirements are given in IEC 61047:

Plug-in converters that are components of lighting fixtures are considered built-in converters, and refer to the additional requirements of lighting standards:
