All-pole sine filters solve EMI problems on frequency inverters
Due to the increase in system networking and in light of Industry 4.0, high-frequency interference pulses pose a constant risk for communication across the entire production process.
Not only does the new SFA all-pole sine filter series from BLOCK solve a multitude of such EMI problems, it also increases the efficiency of drive systems controlled by frequency inverters.
Sine filter for the suppression of differential mode interference and common mode interference. Designed for inverter with DC link connector (+Vg/+Ug), positive or negative or mid point and and works with continuous PWM.
Use of extremly long motor cable lenghts possible
Significant reduction of leakage currents
Elimination of bearing currents
Efficiency optimisaton of the drive system
