Three-phase line reactors ED3N

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. 
Benefits Application
  • Reduction of short-circuit and inrush currents
  • Limitation of di/dt steepness
  • Reduction of current harmonics content 
  • Extended lifetime of rectifier
  • AC drive systems with frequency converters
  • High short circuit power grids
  • Frequency converters without DC-link choke
