June 20, 2016 – New FN5060 dv/dt filters from Schaffner protect AC motors from the effects of peak voltages and inrush amps, “increasing service life and system reliability”, without capacitors or resistors, Schaffner says.

Schaffner says the filters 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. These filters are ideal for loads up to 760 VAC, 30 to 1200A and motors up to 60 Hz. They are also 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).

The products are UL, CE and CSA approved.
