Chokes from TRAMAG

Chokes in the frequency range up to 2,000 Hz

To ensure power quality for trouble-free operation in the drive system, TRAMAG provides single-phase or three-phase chokes according to EN61558, in the frequency range from DC to 2 kHz. We rely on core materials such as iron and ferrites.

Operating voltages up to 7.2 kV and currents up to approx. 10,000 A can be realized technically and economically with copper or aluminum strip windings.
