DV/DT filter, Rated Current 17A ,for 7.5KW Motor
Dv/dt filters Description
The SIKES DV/DT filters decreases the insulation stress of motors by lowering the dU/dt value of the variable speed drive output voltage. It can be utilized with cable lengths up to 100 to 300 m depending on the model.
Moreover, the units are intended for maximum switching frequency of 200 kHz. The filters create less heat with smaller switching frequencies. The motor is not intended for utilizing with a variable speed drive to retrofit applications.
Du/Dt filter is economical alternative for Sine wave filter.
Dv/dt filters can support our customers with:1.effectively reducing the dt/dv voltage of the inverter servo motor ends;
2.preventing the transmission cable and the servo motor coil from early aging and breakdown;
3.extending the service life of the servo motors and operation period and improving the servo’s reliability;
4.reducing the interference to the nearby equipment and circuits;
5.reducing the motor grounding leaking current;
6.reducing the interference when the contactor between filters and the motors is switched on;
7.effectively reducing the peak pulse voltage of the servo motor ends.
8.meeting the output requirements of IEC 60034-17, 60034-25.
