DATASHEET
Sine wave filters FN 5040/FN 5045
LC Sine Wave Filter for Motor Drives
Smooth sine wave without voltage peaks
Perfect motor protection
Reduce bearing currents
Motor frequency up to 200 Hz
Extended motor cable length capability
Approvals
UL 61800-5-1 up to 750 A for FN 5040, 480 A for
FN 5045. For use with AC or DC drives (power
conversion equipment) only
Features and benefits
Performance indicators
Converts the rectangular PWM output voltage of
motor drives into a smooth sine wave with low
residual ripple
Elimination of premature motor damage caused by
high dv/dt, overvoltages, cable ringing, motor
overheating, and eddy current losses
Improves bearing life time because of bearing
currents caused by circulating currents
Complies with IEC 60034-17* and NEMA-MG1
requirements for general purpose motors
Optional with NEMA 1 protective cover
