Three-phase SinECOTM sinusoidal filters

Three-phase SinECOTM sinusoidal filters

Purpose and design

Sinusoidal filters are dedicated for use in drive systems powered by voltage inverters. They restore the sinusoidal shape of the voltage at the inverter output. They reduce degradation of the motor insulation and motor power cable, reduce additional losses and motor noise. In addition, sinusoidal filters relieve the load on the inverter by eliminating parasitic capacitive currents. By agreement, we can supply sinusoidal filters tailored to the needs of the drive system for different switching frequency ranges, different voltages and currents. The chokes that are the key elements of the filters are made with CoreECOTM low-loss multi-slot technology.

Upon agreement, we can manufacture a non- standard device with the required technicalparameters.
The manufacturer reserves the right to make changes to the parameters due to technical product developments.
