Main features
■ Optimized design that takes into account
■ switching frequency, voltage drop and filtering char
acteristics
■ Proven technology ABB has delivered hundreds
of sine filter solutions over the last years
■ Cost effective solution
■ Standard software has all the parameters that need
to set
This means that the output voltage waveform almost
sinusoidal without high voltage peaks.
The ABB sine filter solution can used variety of
applications:
■ Motor does not have adequate insulation for VSD duty
■ Total motor cable length long e. ACS800-04 frame size
R6 pow range, filters are available also with IP23
enclosure class. there
are restrictions to
motor cable length.
Filters are available IP00 degree protection over
