dv/dt Filter FN5060HV

Output Filter for Motor Drives

  • Reduction of drive output voltage dv/dt
  • Reduction of voltage stress at motor windings
  • Protect AC motors from destructive effect of peak voltages
  • Increase of motor service life
  • Improvement of system reliability

Features and Benefits

Efficient reduction of high output voltage dv/dt from IGBT motor drives (as per IEC 60034-17/25)
Restriction of overvoltages caused by line reflections on motor cables (as per IEC 60034-17/25)
Protection of motor winding insulation from premature aging and destruction
Increase service life of electric motors
Patented solution without capacitors and resistors for ease of installation and increased reliability
Less interference propagation towards neighbouring equipment or lines
Output filter with low impedance, ideal for processes requiring exceptional precision and reproducibility of movements

Typical Applications

Motor drive applications with short to medium motor cable length
Machinery comprising servo or torque motors
Submersible- and irrigation pumps
HVAC equipment, incl. pumps, fans and compressors
Elevators, hoisting and cranes
Motor drives for process lines
Applications where sine wave filters are not suited (e.g. high dynamic operation)
