LI-220C
9 kHz to 30 MHz CISPR 16-1-2 / ANSI C63.4 250 & 50 microhenry / 20 Amps
The LI-220C Line Impedance Stabilization Network (LISN) provides the necessary measurement platform for performing power line conducted emissions compliance testing as required by most worldwide standards for commercial products. The LI-220C is compliant with both CISPR 16-1-2 and ANSI C63.4. The LISN provides defined stable impedance and isolates the EUT from power source influences, thereby providing accurate and repeatable results. The LI-220C includes one pair of single-conductor networks, housed together, to be installed in series with each current-carrying conductor in a single-phase, dual-phase or DC power system. A second LI-220C pair can be used to accommodate 3-phase power systems (Wye or Delta configurations). This LISN uses air-core inductors to prevent saturation and permeability variation.
