VLT® All-mode Filter MCC 201
VLT® All-mode Filter MCC 201 output filters are dual mode low-pass sine-wave filters operating differential mode and common mode. These filters suppress the switching frequency component from the drive and smooth out the phase-to-phase and phase-to-ground output voltage of the drive to become sinusoidal.
The VLT® All-mode Filter MCC 201 technology with reduction of differential
mode and common mode interference at the inverter output enables the use of extremely long motor cable lengths. This filter also supports the use of unshielded motor cables.
The VLT® All-mode Filter MCC 201 efficiently filters differential and common mode interferences. Through the connection to the intermediate circuit of the VLT® drive, the common mode currents returns to the source of the drive. This configuration is highly effective at preventing this high-frequency interference current from spreading across the electrical installation.
