IEC61000-3-3 and IEC61000-3-11 Flicker Impedance Networks
IEC61000-3-3 and IEC61000-3-11 Impedance Networks designed specifically for compliant flicker testing, with models ranging from 16Arms single phase to 75Arms three phase.
Unique to the N4L IMP series, all models are compliant to Zref and are supplied with ISO17025 accredited certification of impedance at working current. A proprietary air-core design maintains impedance linearity throughout the operating range and is proven by the working current calibration. By maintaining Zref on all models rather than the typical Ztest approach taken by many suppliers, there is no need to apply a conversion factor and our high current IEC61000-3-11 models maintain the required impedance for ≤ 16Arms IEC61000-3-3 testing, with no need for impedance switching.
