Available Configurations

The Com-Power LI-400 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-400 is compliant with MIL-STD 461-F. The LISN provides defined stable impedance and isolates the EUT from power source influences, thereby providing accurate and repeatable results. The LI-400 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-400 pair can be used to accommodate 3-phase power systems of Wye or Delta configurations. The LI-400 is equipped with IEC connector at the mains and NEMA 5-15R at EUT power output ports. This LISN uses air-core inductors to prevent saturation and permeability variation.

The mounting plate is left unpainted in order to facilitate connection to earth ground in its installation, which is essential due to high leakage current. It has a built-in transient limiter for impedance matching, reduction of out-of-band emissions, and transient protection for your measurement instrument. All Com-Power LISNs are individually calibrated in compliance with the relevant requirements of CISPR 16-1-2 and ANSI C63.4. Impedance, Phase, Isolation, and Insertion Loss data are supplied with each unit, along with a calibration certificate.
