IEC 61000-4-11-2020 pdf free.Electromagnetic compatibility (EMC) – Part 4-11: Testing and measurement techniques – Voltage dips, short interruptions and voltage variations immunity tests for equipment with input current up to 16 A per phase.
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 document 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 AC networks.
It does not apply to electrical and electronic equipment for connection to 400 Hz AC networks. Tests for these networks will be covered by future IEC documents.
The object of this document 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.
NOTE I Voltage fluctuation immunity tests are covered by IEC 61000-4-14.
The test method documented in this document describes a consistent method to assess the immunity of equipment or a system against a defined phenomenon.
NOTE 2 As described in IEC Guide 107, this is a basic EMC publication for use by product committees of the IEC. As also staled in Guide 107. the IEC product committees are responsible for determining whether this immunity test standard should be applied or not, and, it applied, they are responsible for defining the appropriate test levels. Technical committee 77 and its sub-committees are prepared to co-operate with product committees in the evaluation of the value of particular immunity tests for their products.
