FUSS-EMV, 3AFU400 3 x 500 V ac 80A 8kHz Line Reactor

FUSS du/dt-Filters are used to reduce the voltage slew rate at the output of frequency converters to values below 500 V/μs.

du/dt-filters are simple and cheap devices to optimise in a simple drive system.
du/dt filters are damping the rate of change of approx. 10.000 V/sec down to a low rate
This results in a more smooth running drive system with less noise and increases the long life period of a motor.
