DV/DT Filters Extend Service Life of AC Motors

July 7, 2016

FN5060 dv/dt filter protect AC motors from destructive effects of peak voltages and inrush amps, increasing service life and system reliability.

This patented technology protects motors and adjacent equipment without capacitors or resistors, making them simple to install. They efficiently reduce high output dv/dt from IGBT motor drives and eliminate over-voltages caused by line reflections on motor cables, per IEC 60034-17/25.

Typical dv/dt reduction is a factor of 8 to 12. They are ideal for motor drives with short to medium cable lengths, servo or torque motors, submersible or irrigation pumps, HVAC equipment including pumps, fans and compressors, elevators, hoists and cranes, process equipment and applications where sine wave filters are not suited (such as high dynamic operations).

  • ideal for loads up to 760 VAC, 30 to 1200A and motors up to 60 Hz
  • dv/dt reduction is a factor of 8 to 12
  • Easy Installation
