IMP Series – Impedance Networks – N4L

Test and Measurement

N4L have developed a range of IEC61000-3-3 and IEC61000-3-12 Compliant Impedance Networks designed specifically for compliant flicker testing, the range spans from 16Arms units to meet the IEC61000-3-3 standard up to 75Arms 3 phase units to meet IEC61000-3-12. Our impedance networks are force air cooled to ensure minimal temperature drift under high loads and feature air core inductors which prevent saturation at high current.
