Schaffner Sine wave filters for VFDs

These sine wave filters are designed to eliminate premature motor damage caused by high dv/dt, overvoltages, cable ringing, motor overheating and eddy current losses caused by VFDs. Suitable for motor frequencies up to 600 Hz, this technology converts the rectangular PWM output voltage of motor drives into a smooth sine wave with low residual ripple. The filters also can help to improve bearing life by eliminating circulating bearing currents. The product line can accommodate a range of switching kHz and voltage ratings up to 690 Vac.
