to EN 61000-3-2:2014+A1:2019
The European Standard EN 61000-3-2:2014+A1:2019, also referred to as the Electromagnetic Compatibility (EMC) standard, defines the limits and measurement methods for harmonic current emissions produced by equipment that is connected to low voltage public power supply systems. It ensures that the levels of harmonic currents generated by these devices are within acceptable limits, reducing the risk of interference with other electrical equipment sharing the same network.
EN 61000-3-2:2014+A1:2019 applies to various electrical equipment, such as computers, televisions, household appliances, and industrial machinery. Compliance with this standard is crucial for manufacturers to obtain CE marking, indicating their products' conformity with European Union regulations.
Key Requirements of EN 61000-3-2:2014+A1:2019
The EN 61000-3-2:2014+A1:2019 standard sets limits on the harmonic currents that equipment can inject into the public power supply system. Here are some key requirements outlined by the standard:
Harmonic Current Emissions: The standard limits the emission of harmonic currents from equipment operating on an AC power supply. These harmonic currents are caused by non-linear characteristics of the device's power consumption.
Equipment Categories: The standard categorizes equipment into four classes based on their total input power and operating conditions. Each category has different limits for harmonic currents.
Compliance Evaluation: Manufacturers must perform tests to determine their equipment's harmonic current emissions. The test results are then compared against the limits specified in EN 61000-3-2:2014+A1:2019 to ensure compliance.
Benefits of EN 61000-3-2:2014+A1:2019 Compliance
The compliance with EN 61000-3-2:2014+A1:2019 standard brings several benefits for both manufacturers and end-users:
Reduced Electrical Interference: By limiting harmonic currents, this standard ensures that electrical devices do not interfere with each other when connected to the same power supply system. This reduces disruptions, improves performance, and extends the lifespan of electrical equipment.
Enhanced Power Quality: Compliance with the standard leads to improved power quality in the public power grid. It helps maintain stable voltages and currents, preventing fluctuations that can damage sensitive electronic devices.
Market Access: Meeting the requirements of EN 61000-3-2:2014+A1:2019 ensures that products are eligible for CE marking, enabling access to the European market. This opens up opportunities for manufacturers to expand their customer base and increase sales.
