Smoothing chokes 300 Hz

Description

Smoothing chokes ED1W (300Hz) are usually applied in output circuits of three-phase rectifiers. They allow a significant reduction of pulsation of rectified output current. In practice, smoothing chokes are often combined with capacitors and form LC filters.
The following table lists only the sample parameters of some manufactured chokes. After the previous agreement there is a possibility to design chokes with parameters other than those given in the table
