What is IEC 61000-4-11:2019?

IEC 61000-4-11:2019 is an international standard that specifically deals with voltage dips, short interruptions, and voltage variations immunity tests for electrical/electronic equipment connected to low-voltage power supply networks. This standard provides guidelines and specifications to ensure the proper functioning of equipment in the presence of disturbances in the power supply.

Why is IEC 61000-4-11:2019 important?

In today's world, reliance on electrical and electronic equipment is ubiquitous. From household appliances to industrial machinery, almost every aspect of our lives depends on them. It is crucial to ensure that these devices can withstand and operate properly even in challenging conditions. That's why the IEC 61000-4-11:2019 standard holds great significance.

Key aspects of IEC 61000-4-11:2019

The standard primarily focuses on three key aspects:

Voltage Dips: Voltage dips refer to a short-term reduction in the supply voltage level. Such dips can be caused by various factors like sudden load changes or grid faults. The standard defines specific measurement procedures and requirements to test the immunity of equipment against voltage dips.

Short Interruptions: Short interruptions are brief breaks in the power supply. These interruptions can have a significant impact on the performance and reliability of sensitive electronic devices. IEC 61000-4-11:2019 provides guidelines to ensure equipment can tolerate such interruptions without any adverse effects.

Voltage Variations: Voltage variations encompass both fluctuations and rapid changes in the supply voltage. Equipment connected to power supply networks must be capable of withstanding these variations for uninterrupted operation. The standard sets out specific test procedures and limits to evaluate the immunity of equipment against voltage variations.

Compliance with IEC 61000-4-11:2019

To ensure the proper functioning and reliability of electrical/electronic equipment, compliance with the IEC 61000-4-11:2019 standard is crucial. Manufacturers need to thoroughly test and validate their products against the specified requirements outlined in the standard. Compliance not only enhances the quality and performance of equipment but also improves user satisfaction and safety.
