IEC 61000-4-11 - In Compliance Magazine

« Back to Glossary Index

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 not exceeding 16 A per phase, for connection to 50 Hz or 60 Hz a.c. networks. It does not apply to electrical and electronic equipment for connection to 400 Hz a.c. networks. Tests for these networks will be covered by future IEC standards. The object of this standard is to establish a common reference for evaluating the immunity of electrical and electronic equipment when subjected to voltage dips, short interruptions and voltage variations.

New Voltage Sag Testing Requirements for Industrial Equipment
EMC Management in Charging Applications
Implementing a process of EMC compliance for a specific project is much more than simply ensuring that the design engineers follow a long list of “do’s and don’ts” in the form of EMC design rules. Following this process will reap benefits when EMC performance is evaluated at the end of the design process.
Performing Proximity Magnetic Fields Immunity Testing
This article summarizes the changes in IEC 60601-1-2:2014 Amendment 1:2020 and describes how to conduct proximity magnetic fields immunity testing as required by the standard.
New Voltage Sag Testing Requirements for Industrial Equipment
Immunity from voltage sags is vital for reliable operation of our ever more sophisticated electronic controls and equipment. Every electrical product should be able to ride through typical voltage sags, but in many cases the first sag test occurs after equipment is installed and in operation. Select the appropriate sag immunity specification and equipment compliance testing, and you’ll be glad you did.
