FN 322A-3/01
The Schaffner FN 322A-3/01 is an electronic filter manufactured by Schaffner. It is a three-phase active harmonic filter that uses an integrated three-level active voltage conditioner (LVDF) to reduce up to 99.5% of current harmonic distortion up to the 25th Harmonic. It is designed for use in Variable Frequency Drive (VFD) applications and is designed to provide a sinusoidal input current waveform and to reduce line current distortion. The FN322A-3/01 has a three-phase input and output with a rated current of 303A, Rated current of 1000A, Rated power of 250kW, Rated voltage of 500V, and Frequency range of 45-66Hz. It provides a six-pulse rectifier configuration with rated input power of 250 kW. The filter features an easy to use and robust aluminum alloy enclosure, active harmonic filtering, under- and overvoltage protection, phase and power quality monitoring, power factor correction.
