The dV/dT output filter is specially designed for frequency inverters, inverters, speed control systems, etc …
The dV/dT filter is designed to protect AC motors from the damaging effects that long cable lengths can cause between the drive and the motor. Depending on the switching frequency of the IGBTs used in a drive and the size of the motor, cable lengths of more than 15 meters can lead to voltage spikes in the motor, which exceed the nominal value of the motor’s insulation system. .
Typical applications include submersible pumps, HVAC equipment, and process automation lines. NEMA B standard motors, MG1Part 30, are prone to failure as a result of high voltage spikes and can benefit from using a dV/dT filter.
Reduces leakage current.
It is the ideal complement between the variator and the motor.
