The cyclical output voltages of frequency inverters produce additional losses in motor leads and windings which can significantly affect the reliability and longevity of motor insulation.

KEB COMBILINE sinusoidal output filters limit stresses to admissible limits and provide the required protection of lacquer insulation and end connections particularly for long motor leads and special motors.

The protection offered by sinus filters is particularly important for the retrofitting of already installed older motors with frequency inverters to optimise the efficiency of existing systems.

The sinus filter range includes the following versions:

sinusoidal output filter f_max = 100 Hz
sinusoidal output filter f_max = 200 Hz
sinusoidal output filter f_max = 400 Hz
and customer-specific versions for output frequencies up to 1600 Hz.
