Emi filter 50A noise rfi mains electronical filters for VFD and converter
EMI Power Line Filter from the LC low-pass passive network components.It uses principles of impedance mismatch,so that by
the attenuation of electromagnetic interference signals.
Filter filtering effect depends on the extent of impedance mismatch,the greater the impedance difference, the better the
filter. For example,to get better results, for low-impedance power supply side, should be accompanied by a high input
impedance of the filter;pairs of high input impedance of the load side, then the filter with low output impedance.

Leakage current
Leakage current: at a given voltage and frequency, the current flow between the filter-phase line or the midline and ground.
Under normal circumstances, leakage current from the grounded capacitors (Y capacitor) is caused due to security
considerations, a variety of different testing standards for various types of equipment, leakage current from the strict 1
imitations. In particular, medical equipment, in choosing a filter, be sure to take full account of the leakage current.
Leakage current typically 250VAC 50HZ, below the ambient temperature is 20°C measured. Works as follows:
Low leakage current to meet with medical machine special requirements.
Applicable to suppressing noise and high frequency harmonic in power.
Low leakage current with high insert lose of noise.
Control EMI interference between line and line,line and ground.
Available for electronic equipments and measuring instruments.
