DIN EN IEC 61347-1:2025-12

This document specifies general safety requirements for control gear for electric light sources for use on DC supplies up to 1 500 V or AC supplies up to 1 000 V at 50 Hz or 60 Hz. This document also applies to control gear used for electric light sources in which optical radiation is generated using the same technology as that used for various lighting purposes and for the generation of radiation outside of the visible spectrum insofar as such control gear falls within the scope of the relevant Part 2. This document applies only in conjunction with the relevant Part(s) 2. The standard differs from DIN EN 61347-1 (VDE 0712-30):2021-08 as follows: a) complete review of document structure, including but not limited to what is individually described under items b) to s); b) removal of requirements for electromagnetic controlgear; c) addition of more specific requirements for control circuit insulation and corresponding marking; d) merging of thermal test requirements for transformers into a new Clause 16; e) clarification of specifications for the moisture resistance test; f) update of the normative reference to standards of the transformer series IEC 61558; g) correction of the normative reference for PCB testing with respect to flames and fire; h) update of further normative references where appropriate; i) allowance of an alternative DC electric strength test; j) addition of specific provisions for the use of bridging capacitors; k) update of fire hazard testing requirements; l) introduction of requirements for PELV applications; m) clearance distances now generally based on peak instead of RMS voltage values; n) introduction of a new type of protected emergency lighting controlgear; o) review and clarification of touch current and voltage requirements; p) clarification of the test sequence for independent controlgear with respect to the application of the IEC 60598 series versus the IEC 61347 series; q) introduction of reduced touch voltages and currents for interrupted DC voltage applications or pulse width modulation (PWM); r) changes concerning the recommendations for electric strength routine testing; s) merging of requirements for safety isolating controlgear from former Annex L into the main body of the document; t) introduction of Annex N intended to address touch current measurement; u) introduction of Annex O intended to provide information on document reorganization. This document applies to the general safety requirements for controlgear for electric light sources. Controlgear for electric light sources represents a device connected between the power supply and at least one light source in order to supply power to the light source(s). The controlgear may be partially or fully integrated into the light source.
