VLT® Sine-wave Filter
MCC 101
„ VLT® Sine-wave Filters are positioned bet-
ween the AC drive and the motor to provide
a sinusoidal phase-to-phase motor voltage
„ Reduces motor insulation stress
„ Reduces acoustic noise from the motor
„ Reduces bearing currents (especially in large
motors)
„ Reduces losses in the motor
„
Prolongs service lifetime

VLT® dU/dt Filter MCC 102
„
Reduces the dU/dt values on the motor
terminal phase-to-phase voltage
„ Positioned between the AC drive and the
motor to eliminate very fast voltage chan-
ges
„ The motor terminal phase-to-phase voltage
is still pulse shaped but its dU/dt values are
reduced
„ Reduces stress on the motor's insulation
and are recommended in applications with
older motors, aggressive environments or
frequent braking which cause increased DC
link voltage

VLT® Common Mode Filter
MCC 105
„ Positioned between the AC drive and the
motor
„ They are nano-crystalline cores that mitigate
high-frequency noise in the motor cable
(shielded or unshielded) and reduce bearing
currents in the motor
„ Extends motor bearing lifetime
„ Can be combined with dU/dt and sine-wave
filters
„ Reduces radiated emissions from the motor
cable
„
Reduces electromagnetic interference
„ Easy to install – no adjustments necessary
„ Oval shaped – allows mounting inside the
AC drive enclosure or motor terminal box
Power range
380-415 V AC (50 and 60 Hz)
440-480 V AC (60 Hz)

VLT® Line Reactor MCC 103
„ Ensures current balance in load-sharing ap-
plications, where the DC-side of the rectifier
of multiple drives is connected together
„ UL-recognized for applications using load
sharing
„
When planning load-sharing applications,
pay special attention to different enclosure
type combinations and inrush concepts
„ For technical advice regarding load-sharing
applications, contact Danfoss application
