Product Description.
Power EMI filter is a reactance low-pass filter, installed in the power inlet and outlet of electronic equipment, both to suppress the noise interference transmitted in through the power line of the grid, but also to suppress the high-frequency interference signal generated by the electronic equipment itself into the grid, endangering other electronic equipment. Therefore EMI has become the electronic equipment must be installed in the device.
Power noise is a kind of electromagnetic interference, the spectrum of the conducted noise is roughly 10kHz ~ 30MHz, up to 150MHz. according to the direction of propagation, power noise can be divided into two categories: one is introduced from the power line into the external interference, the other is generated by the electronic equipment and the noise conducted by the power line out. This shows that the noise is a two-way interference signal, electronic equipment is both the object of noise interference, but also a noise source. If you look at the formation characteristics, noise interference is divided into two kinds of series-mode interference and common-mode interference. Series-mode interference is between two power lines (referred to as line-to-line) noise. Common mode interference is two power lines to the earth (referred to as the line to ground) noise. Therefore, EMI filters should meet the requirements of electromagnetic compatibility (EMC), but also must be a two-way RF filter, on the one hand, to filter out external electromagnetic interference introduced from the AC power line, on the other hand, can also avoid their own equipment to the external noise interference, so as not to affect the normal work of other electronic equipment in the same electromagnetic environment. In addition, the electromagnetic interference filter on the series mode, common mode interference have played a suppression role.
Precautions.
EMI filter selection should consider its operating voltage, operating current, withstand voltage value
EMI filter should be installed at the power supply entrance location to reduce radiation interference
EMI filter connection line use double rubber line is good, it can eliminate part of the high frequency interference signal
EMI filter input and output lines should not be parallel, need to pull away a certain distance to ensure the function of the filter
EMI filter E point and chassis shell must be in good contact, and connected to the ground wire
