What is EN 61800-3:2020?

EN 61800-3:2020 is a technical standard that provides guidelines and requirements for electromagnetic compatibility (EMC) of adjustable speed electrical power drive systems. It defines the minimum specifications for emissions and immunity levels, ensuring smooth operation of equipment while reducing the risk of interference between different electronic devices. This article will explore the key aspects and implications of this standard in detail.

Importance of EN 61800-3:2020

The implementation of EN 61800-3:2020 is crucial to ensure the compatibility and reliability of electrical power drive systems in various industry applications. With the increasing use of electronic devices and motor-driven equipment, it is essential to address the potential risks of electromagnetic disturbances. Compliance with this standard not only guarantees the safety and performance of equipment but also aids in legal compliance, facilitating trade across international markets.

Emissions and Immunity Levels

One of the key elements of EN 61800-3:2020 is the definition of acceptable emission and immunity levels. Emissions refer to the amount of electromagnetic energy released by a device, while immunity refers to its ability to withstand external electromagnetic fields without malfunctioning. The standard sets limits for emissions to ensure they do not interfere with other devices nearby, and for immunity to guarantee proper functioning even in the presence of external disturbances.

Implementation and Certification Process

To comply with EN 61800-3:2020, manufacturers need to implement appropriate measures during the design and manufacturing phase of electrical power drive systems. This may include shielding, grounding, filtering, and using appropriate components to reduce emissions and increase immunity. Once the systems are developed, they undergo testing by accredited laboratories to ensure conformity with the specified requirements. A successful certification indicates that the products are compliant and can be safely used in various applications.
