The LI-325 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-325 is compliant with both RTCA DO-160 and MIL-STD 461.

The LISN provides defined stable impedance and isolates the EUT from power source influences, thereby providing accurate and repeatable results. The LI-325 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-325 pair can be used to accommodate 3-phase power systems (Wye or Delta configurations).

The LI-325 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-325 is left unpainted in order to facilitate connection to earth ground in its installation, which is essential due to high leakage current.

All Com-Power LISNs are individually calibrated in compliance with the relevant requirements of RTCA DO-160 and MIL-STD 461. Impedance and Insertion Loss data is supplied with each unit, along with the calibration certificate.

Features:
  • Frequency range: 10 kHz to 400 MHz
  • Fully compliant with RTCA DO-160 / MIL-STD 461
  • "Air-core" inductors to prevent saturation
  • Individual Calibration Included
  • Three Year Warranty
