Customized line reactors with different electrical and mechanical specifications are available on request.
* Calculated at rated current, 400 VAC and cos phi=0.8. The exact value depends upon the efficiency of the drive, the motor and the entire application.
** Power loss at 25°C/50 Hz, considering a typical harmonic spectrum of a motor drive with B6U rectifier bridge.
Harmonics reduction
Line reactors are a cost-effective way for the limitation of mains harmonics. The harmonics reduction capability is related to the reactor impedance. A higher
impedance translates directly into lower harmonic currents, but of course also into a larger component with a higher voltage drop − and vice versa.
4% impedance reactors like RWK 212 provide an excellent cost/benefit ratio and are particularly beneficiary in the most diverse motor drive applications.
The table below shows various reactor impedance values and their calculated effect in terms of harmonics reduction.
