Title: What is EN 61000-4-4:2019 and EN 61000-4-9:2020?

Introduction:

The ability of electrical and electronic equipment to withstand sudden surges of electromagnetic energy without malfunctioning or being damaged is critical. This is where Electromagnetic Compatibility (EMC) comes in. EN 61000-4-4:2019 and EN 61000-4-9:2020 are two international standards that help ensure the immunity of electrical and electronic devices to impulses from sources such as lightning strikes, power line faults, and switching transients. In this article, we will discuss the purpose of these standards, the key requirements of EN 61000-4-4:2019 and EN 61000-4-9:2020, and the significance of adhering to these requirements.

Purpose of EN 61000-4-4:2019 and EN 61000-4-9:2020:

The primary purpose of EN 61000-4-4:2019 and EN 61000-4-9:2020 is to ensure that electrical and electronic devices can withstand sudden surges of electromagnetic energy without malfunctioning or being damaged. These standards provide guidelines for evaluating the susceptibility of equipment to impulse interference and the immunity to electrical and electronic transient phenomena (ECTP), which can be generated by various sources such as lightning strikes, power line faults, and switching transients.

Understanding Electrostatic Discharge (ESD):

Electrostatic discharge (ESD) refers to the sudden flow of electricity between two electrically charged objects. It occurs when there is a difference in electric potential between the objects and results in a rapid transfer of electrons. ESD can be generated by various sources such as friction, contact, or induction. While harmless in everyday situations, ESD can cause severe damage to sensitive electronic components and systems, leading to malfunctions or complete failure.

The Significance of EN 61000-4-2:2020:

EN 61000-4-2:2020 sets forth a series of test methods and performance criteria to evaluate the immunity of electrical and electronic equipment to ESD. Compliance with this standard ensures that products are capable of withstanding ESD events without suffering detrimental effects. By adhering to these requirements, manufacturers can enhance the reliability and durability of their products, preventing costly returns, repairs, and potential safety hazards caused by ESD-induced failures.

Key Requirements of EN 61000-4-4:2019 and EN 61000-4-9:2020:

Understanding the requirements of EN 61000-4-4:2019 and EN 61000-4-9:2020 is essential for ensuring the safety and reliability of electrical and electronic devices. Here are some of the key requirements of these standards:

Immunity to Impulse Interference:

The primary objective of EN 61000-4-4:2019 and EN 61000-4-9:2020 is to ensure that electrical and electronic devices are resistant to impulse interference. This means that the devices should not malfunction or be damaged by sudden surges of electromagnetic energy.

Immunity to Electrical and Electronic Transient phenomena (ECTP):

EN 61000-4-4:2019 and EN 61000-4-9:2020 also provide guidelines for the immunity of electrical and electronic devices to electrical and electronic transient phenomena (ECTP), which can be.
