IEC 61000-4-11 Testing – Dips, Interruptions & Voltage Variations Immunity

The IEC 61000-4-11 test standard and EN 61000-4-11 test standard 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. The scope of IEC 61000 4 11 testing 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.

The EN 61000 4 11 test standard states that electrical and electronic equipment may be affected by voltage dips, short interruptions or voltage variations of power supply. Voltage dips and short interruptions are caused by faults in the network, primarily short circuits, in installations or by sudden large changes of load. These phenomena are random in nature and can be minimally characterized for the purpose of laboratory simulation in terms of the deviation from the rated voltage and duration.

Keystone Compliance is recognized as a leading IEC 61000-4-11 test lab. With five EMC test chambers and six ground plane surfaces, lead times for scheduling are short. Testing is streamlined and having dedicated report writers, EMC test reports are typically distributed within one week after testing is complete. The primary reason why so many manufacturers have made Keystone Compliance their EN 61000-4-11 testing lab is our engineering guidance throughout the test program. Our engineers work directly with customers who are experiencing challenges in meeting the EMC test requirements. With a vast experience of testing to standard like EN61000-4-11, our team is able to quickly identify the issues and suggest corrections. This EMC design guidance is unparalleled.
