EMI Protections

They serve to protect the devices from disturbs in frequency that are present on the electrical network. In particular they are necessary (in order to pass the homologation tests) in the DIMMER, in the SWITCHING power supply, etc, considered apparatuses that disturbs the net. Moreover they can also be used for protecting a device from eventual income disturbs.

They can be self made using resistances and, condensers and particular reels (generally in the locals power supply these are made for having the possibility to plan a specific filter and to intervene in the phase of certification) or they can be already found in commerce.

The connection of various parts, in the different levels of protection, will render your circuit protected towards a more or less disturbs band.
