Harmonic current emission standard IEC 61000-3-2 released the latest version 2018
Recently, the IEC IEC Technical Branch TC 77/SC77A-EMC-Low frequency phenomena released the fifth edition of the harmonic current emission standard IEC 61000-3-2:2018, the new standard release date is 2018-01-26, replacing the existing fourth edition of IEC 61000-3-2:2014 "Electromagnetic compatibility (EMC) -Part 3-2:Limits-Limits for harmonics" C current emissions (equipment input current is less than 16 A per phase).
This standard is applicable to electrical and electronic equipment with an input current of not more than 16A per phase connected to a common voltage distribution system. The changes in the new standard are mainly reflected in the great differences in lighting requirements. Therefore, manufacturers concerned with lighting products need to pay attention to the latest changes in the standard. Compared with IEC 61000-3-2:2014, lighting The main technical changes in the equipment sector are as follows:
1. Update the emission limits of lighting equipment with rated power of less than 25W, taking into account the new lighting equipment;
2, increase the critical value of 5W, lighting equipment less than 5W no emission limit;
3. Modification of the requirements for dimmer used in non incandescent lamps.
4, increase the digital load side (DLT) transmission control device test conditions;
5. Cancel the use of reference lamp and reference ballast for lighting test.
6. Simplify and clarify the terminology of lighting.
7, classify the stage lighting and professional luminaries used for studio as class A;
8. Clarify the classification of emergency lighting.
9, the lighting device contains an active input power less than 2W control module description.
10. In order to be consistent with IEC 61000-3-12, the range of IEC 61000-3-2 is changed from the equipment with input current <16A to the equipment with rated input current <16A.
In the new version of the standard rated power 5W < P < 25W of new lighting equipment (such as LED control devices and luminaires) need to increase testing, involving a wide range of products, such as some low-power LED lighting products, including: LED desk lamps, LED bulbs, LED tubes, etc. need to increase testing.
