Three Phase EMI Noise Filter
Yanbixin 3-Phase EMI Noise filters reduce unwanted electromagnetic
interference (EMI) noise within the conducted area of
electromagnetic susceptibility for such applications as frequency
converters, motor drives, and machine tools. Rated from 3 to 500A,
RFI line filters are available for Delta or WYE wiring with a
variety of terminal connection options. These filters are used in
many different applications such as industrial machinery, factory
automation equipment, servo drives, and variable frequency.
YX81G3-30A-S is the Three Phase M4 Screw Output EMI Filter,Compact
small footprint design (bookshelf and chassis mount) saves space
and cost,suppresses EMI noise, filters high current and voltage
EMI.
