Three phase line reactor

AC line reactors are added to the input of the drive and placed in series with the incoming line. They help to mitigate harmonics and because they are between the line and the drive, they are able to act as a buffer for surges and other transients. The intended purpose of a line reactor is not to offer high levels of surge protection and, if greater protection is desired, a dedicated protective device is a much better solution.

Passive Filter

FN 3416 (50 Hz) models of the ECOsine product family represent the very compact “economy line” with a THID performance of ≤10 % (with Ldc). They are ideal for non-linear three-phase equipment with B6 rectifier front-end that do not require the industry leading <5 % THID performance provided by Schaffner ECOsine.
