EATON INDUSTRIES (CANADA) CO VIK80A01 DV/DT FILTER FOR AFDRIVE N1 80A

Output Filter with peak voltages on a 480 V system can reach 1600 V, and on a 600 V system can reach 2100 V. These high peak voltages will cause a rapid breakdown of motor insulation, leading to motor failure. The V1K dV/dt filter is an output device that prevents voltage spikes from variable frequency drives (VFD) from exceeding 1000 V. The V1K minimizes these voltage wave amplitudes and slows the rate of voltage increases.
