Schaffner Motor Drives Improve Performance

Schaffner introduces the FN510 dv/dt filter which eliminates premature motor damage caused by high dv/dt, over-voltages on motor cables, motor overheating and more, to prolong service life motors in high precision environments.  Suitable for motors from 1.5 to 30 Kw with frequencies up to 400 Hz (4 to 24A) or to 200Hz (33 to 66A), this proven technology reduces high output voltage dv/dt from IGBT motor drives and restricts over-voltages caused by line reflections on motor cables.  In addition to providing efficient motor and insulation protection, the FN510 includes an IP20 housing and touch-safe terminal blocks which contribute to overall equipment safety. Typical applications include servo drives, closed loop vector drives, machinery with servo or torque motors, robotics, pick-and-place machinery, motors with short to medium cables, and applications where sine wave filters are not applicable. 

Temperature monitoring and an internal cooling fan protect the filter from thermal overload. The FN510 eliminates the interference propagation towards components or conductors in the vicinity.  They are easily installed and provide immediate results. Models are available to accommodate switching frequencies of 2 to 16 kHZ.  Meets UL 1283, CSA 22.2 No. 8 1986, IEC/EN 60939. 

Schaffner FN510 filters are part of an extensive family of dv/dt filters and sine wave filters which improve motor-drive performance for applications where long cable lengths are a concern, even up to 690 vac.
