Schaffner’s new FN530 Sine Wave Filter with EMC Output Filter eliminates premature motor damage caused by high dv/dt, overvoltages, cable ringing, motor overheating and eddy current losses in industrial applications. Suitable for motor from 1.5 to 7.5 kW and from 4-16 A, with frequencies up to 200Hz, this technology converts the PWM output voltage of motor drives into a smooth sine wave with low residual ripple. In addition to providing efficient motor protection, the FN530 can improve bearing life by eliminating circulating bearing currents, and allow the use of very long unshielded motor cables.
Typical applications include chemical and petro-chemical facilities, semi-conductor manufacturing, mission critical applications, installation with multiple motors in parallel, retrofits of motor drives into existing installation with old wiring and motors, and motor drives with extremely long motor cables (up to 1000 m max).
The FN530 eliminates the interference propagation towards components or conductors in the vicinity. Various models are available to accommodate switching frequencies of 6 to 20 kHZ, and vdc link voltage ratings up to 850 VDC max. Meets UL 1283, CSA 22.2 No. 8 1986, IEC/EN 60939. Model FN530 Sine Wave filters with EMC Output Filter are offered enclosed and feature IP20 protection. They are easily installed and provide immediate results.
