IEC 61347-1:2024

Controlgear for electric light sources - Safety - Part 1: General requirements

OVERVIEW

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.
