Three-phase line reactors ED3N
Function
The line reactor increases the impedance at the connection point of the frequency converter. As a result, the current consumed by the converter has a lower value of the THDi distortion coefficient, which reduces its effective value. ED3N reactor helps to eliminate negative effects of transients, limiting steepness and peak value of current pulses. 4% reactors are mainly used in drives without a built-in DC-link choke.
