LI-125A 150 kHz to 30 MHz CISPR 16-1-2 / ANSI C63.4 50 µH / 25 Amps
The LI-125A 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-125A 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-125A includes one pair of, separately housed, single-conductor networks, to be installed in series with each current-carrying conductor in a single- phase, dual-phase or DC power system.
A second LI-125A pair can be used to accommodate 3-phase power systems (Wye or Delta configurations). The LI-125A is equipped with Superior Electric SUPERCON® shrouded sockets at the mains (power input) and EUT (power output) ports. The matching color-coded plugs for connection to the mains and EUT wiring are included. This LISN uses air-core inductors to prevent saturation and permeability variation. The mounting plate of the LI-125A is left unpainted in order to facilitate connection to earth ground in its installation, which is essential due to high leakage current.
Frequency range of 150 kHz to 30 MHz
