Schaffner Sinusoidal FN5040/45 drive output filters

The Schaffner Sinusoidal FN5040/45 output filters are designed to ensure cooler and more reliable drives. As well as offering the capacity to prevent premature failures and expensive downtime, they are matched to the technical requirements of modern drive systems reducing the extra losses experienced in AC motors.

The sinusoidal output filters smooth the modulated output voltage of drives and provide the motor with a clean sinusoidal voltage with low residual ripple, in turn preventing premature ageing and destruction of the AC motor.

The Sinusoidal FN5040/45 output filters are available in a compact open frame design (FN5040) or as a user-friendly packaged version (FN5045 - IP20). Both models are designed for rated currents of 4.5 to 1200 A and for up to 500 VAC (±10%). The cable-shield support brackets that are integrated into the housing ensure savings on installation time and costs.
