Enerdoor is an international leader in the design and manufacturing of EMI-RFI filters
Electromagnetic interference (EMI), or radio frequency interference (RFI), is a type of electric or electronic emission that can degrade, impair or prevent electrical circuit performance.
EMI filters are used to suppress interference generated by the device, or by other equipment, and to protect a device from electromagnetic interference signals present in the environment. Most EMI filters consist of components that suppress differential and common mode interference.
To protect and optimize equipment, Enerdoor EMI-RFI filters provide solutions in three product categories: single-phase, three-phase, and three-phase plus neutral filters.
Electromagnetic Compatibility (EMC) refers to the ability of equipment or systems to operate in an electromagnetic environment without introducing intolerable electromagnetic interference to anything in the environment. EMC includes two important aspects: emission and immunity.
Emission: The phenomenon by which the electromagnetic energy is emitted from a source such as a device, machine or system and shall not emit undesirable electromagnetic
interference of a higher level than those allowed by the European EMC Directive 2014/30/EU (See Figure 1).
Immunity (To Interference): The capability of a machine, equipment or system to correctly operate without degrading functional characteristics when affected by electromagnetic interference.
Many countries have established regulations to minimize the radio-frequency interference between electronic equipment including: the CE mark in Europe, FCC in the United States, CCC in China, VCCI in Japan, RCM in Australia & New Zealand, and KCC in South Korea.
The global guideline for electromagnetic interference is the European Directive 2014/30/EU which requires that manufacturers of industrial machine tools and electric and electronic equipment comply with the electromagnetic compatibility emission and immunity Standards.
