The LI-3P-2x Series consists of four separate models of four conductor, 50Ω, 50/250 μH +5Ω Line Impedance Stabilization Networks (LISNs); also known as Artificial Mains V-Networks (V-AMNs). The primary differences between the four models are their respective current ratings: LI-3P-216 16 Amps (per line, continuous) LI-3P-232 32 Amps (per line, continuous) LI-3P-263 63 Amps (per line, continuous) LI-3P-2100 100 Amps (per line, continuous)

These LISNs provide the necessary measurement platform for performing power line conducted emissions compliance testing per most worldwide commercial EMI/ EMC requirements, such as FCC (U.S.), CE (Europe), AS/NZS (Australia/New Zealand), VCCI (Japan), Industry Canada, etc. The LISNs perform the following functions: provide a defined,stable power line impedance across its frequency range for the Equipment Under Test (EUT); isolate the EUT and measurement circuitfrom the power source, thereby minimizing its influence on the measurements; and, couple the disturbance voltages to the coaxial measurement port, which connects to the measuring instrument.

The LISNs use air-core inductors to prevent saturation and permeability variation. The mounting plates are left unpainted in order to facilitate connection to earth ground in their installation, which is essential due to high leakage currents. The side panels for each LISN are louvered for cooling purposes. The LI-3P-263 and LI-3P-2100 also include two internal cooling fans operated by a switch on the rear panel
