TOKIA LF-320 Noise Filter LF320

Description:

The TOKIA LF-320 Noise Filter is used in industrial electrical systems to suppress electromagnetic interference (EMI) and radio frequency interference (RFI) on three-phase power lines, improving equipment reliability and reducing electrical noise. Commonly installed in industrial control panels, CNC machines, variable frequency drives, injection molding machines, and factory automation equipment. Maintenance teams, OEMs, and system integrators use this noise filter for repair, retrofit, expansion, or replacement of industrial EMI suppression systems.

Applications:

The TOKIA LF-320 Noise Filter is commonly used in industrial control cabinets, VFD-driven motor systems, CNC machinery, robotics, packaging equipment, and factory automation systems where reduction of conducted electrical noise is required. The LF Series is designed to improve electromagnetic compatibility (EMC) and protect sensitive electronic equipment from line noise while helping meet industrial EMC requirements.
