The FCD external power line filters provide three-phase filtering for frequency inverters and variable speed motor drives. Designed for very noisy Delta applications, they attenuate conducted interference at low- and high-frequency ranges and protect programmable logic controllers from RF noise on the AC power line. These filters perform best when installed on the line side of the motor drive. The FCD filters prevent noise from returning to the line, enabling equipment to meet strict European regulations on RFI. Suited for field wiring applications, these filters are ideal for EMC troubleshooting and field refurbishing. The FCD filters feature side flanges for easy mounting and DIN type terminals, which eliminate live metal parts allowing safe and easy connections. They also can be sold as an accessory item to motor drives sold in Europe.
