Du/dt filter for motor protection
200 - 690 V, 24 - 2 300 A |
Danfoss VLT Drives
du/dt filters reduce the du/dt values on the motor terminal phase-to-phase voltage - an issue that is important for short motor cables.
The du/dt filters reduce the motor insulation stress and are recommended in applications with risk of flashover.
Compared to sine-wave filters, du/dt filters cut off frequencies above the switching frequency. Having small inductance and capacitance, the price of the filter is lower.
