EVS-EN 61000-4-34:2007/A1:2010

This part of IEC 61000 defines the immunity test methods and range of preferred test levels for electrical and electronic equipment connected to low-voltage power supply networks for voltage dips, short interruptions, and voltage variations. This standard applies to electrical and electronic equipment having a rated input current exceeding 16 A per phase. It covers equipment installed in residential areas as well as industrial machinery, specifically voltage dips and short interruptions for equipment connected to either 50 Hz or 60 Hz a.c. networks, including 1-phase and 3-phase mains. NOTE 1 Equipment with a rated input current of 16 A or less per phase is covered by publication IEC 61000-4-11. NOTE 2 There is no upper limit on rated input current in this publication. However, in some countries, the rated input current may be limited to some upper value, for example 75 A or 250 A, because of mandatory safety standards. It does not apply to electrical and electronic equipment for connection to 400 Hz a.c. networks. Tests for equipment connected to these networks will be covered by future IEC standards.
