BS EN IEC 61000-4-11:2020

1   Scope 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.
