IEC 62041:2010 sets forth the electromagnetic compatibility (EMC) requirements for transformers, power supplies, reactors, and similar products. This standard covers a wide range of equipment, including power transformers, auto – transformers, and power supplies, and applies to products with rated input voltages not exceeding 1000 V AC or 1500 V DC. It defines both emission and immunity requirements, aiming to ensure that these products do not cause electromagnetic interference to other equipment and can maintain normal operation in an electromagnetic environment. The standard also classifies the operating environments into different categories, each with specific EMC limits and test methods.
The emission requirements in IEC 62041:2010 focus on limiting the electromagnetic disturbances generated by the products, such as conducted and radiated emissions. Meanwhile, the immunity requirements specify the ability of these products to withstand electromagnetic disturbances from external sources. By establishing these EMC requirements, the standard helps to ensure the compatibility and reliable operation of transformers, power supplies, reactors, and similar products in various electrical and electronic systems, promoting the overall electromagnetic environment stability.
