What is en 61000 4 5 surge immunity ?

Power surges are a common problem for sensitive electronic devices. They can cause data loss, disrupt critical services, or even expensive repairs. To address this issue, the International Electrotechnical Commission (IEC) has developed the EN61000-4-5 standard, which specifies the requirements and test methods for electrical and electronic equipment to withstand surges caused by atmospheric disturbances or switching operations.

EN61000-4-5 surge immunity is a critical aspect of ensuring the reliability and safety of these devices. It defines test levels for both voltage surges conducted through power supply lines and surges induced by electromagnetic fields. Compliance with this standard is often a regulatory requirement for electronic devices sold in many countries.

The standard ensures that devices are designed and manufactured to withstand common surge events. It takes into account the intensity, duration, and the vulnerability of the affected equipment. High-energy surges can cause immediate damage, while low-energy surges may gradually degrade component reliability over time. In sensitive electronic devices, such as computers, HVAC systems, or medical equipment, power surges can lead to data loss, disruption of critical services, or expensive repairs.

EN61000-4-5 standard is a comprehensive set of requirements that outlines the testing procedures for surge immunity. It provides a standardized method for evaluating the ability of electrical and electronic equipment to withstand power surges, which can help identify components that may be prone to power surges and improve overall system reliability.

3. How does EN61000-4-5 Surge Immunity standard work?The EN61000-4-5 standard is divided into four main parts:A, B, C, and D.

Part A provides the general requirements for the standard, including the scope, testing methods, and definitions.

Part B specifies the requirements for surge immunity tests, including the types of tests to be conducted and the requirements for test equipment.

Part C defines the requirements for reporting and documenting the results of the tests.

Part D specifies the requirements for the testing procedures, including the testing equipment, the testing conditions, and the testing procedures themselves.

The standard also includes an appendix that provides additional information and definitions.
