• Newtons4th Ltd-IEC61000-3-3 and IEC61000-3-11 Flicker Impedance Networks

N4L have developed a range of IEC61000-3-3 and IEC61000-3-11 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 IEC61000-3-11. 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.
