FV Input Filters
|
FV input filters are aimed for equipment protection from high voltage interference in three phase circuits AC with 380V voltage. Also such filters reduce on-line current harmonic distortion. Filters consist of three phase inductance choke and voltage control resistor for each phase. These filters are used mostly for as an input filter for electric drives. Filter output capacity makes from 1,5 to 45 kW (depending on the modification).
