IEC 61347-1:2024 specifies general safety requirements for controlgear 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 fourth edition cancels and replaces the third edition published in 2015 and Amendment 1:2017. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
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.
