DV/DT Filter

A cost-efficient solution for minimising the du/dt increase

REO du/dt filters suppress the voltage increase to tolerable levels due to their design.

For short lengths of cable between the frequency inverter and the motor, a du/dt filter limits the
increase speed and is the ideal link between frequency inverter and motor.
