L3-32
The AMN - Artificial Mains Network, also known as LISN - Line Impedance Stabiliza-
tion Network - is the ancilliary device intended for repeatable and accurate measure-
ment of the disturbance voltage that an EUT (Equipment Under Test) may inject into
the power line or mains.
This is obtained by providing well known impedance value and phase response across
the frequency range of the test.
L3-32 is suitable for measurement on AC 3-phase power circuits from DC to 60 Hz.
The equivalent V-Network circuit of 50 Ω // (5 Ω + 50 μH) with 250μH choke is fully
compliant
with the reference standards.
PMM Artificial Mains Networks provide robust and stable mechanical construction,
high quality electric components, easy and perfect grounding, solid input-output pow-
er connections. They can be used in conjunction with any EMI receiver or spectrum
analyzer and offer features required for safe, repeatable and accurate measurements.
