LISN for DO-160, MIL-STD 461, CISPR 25 & 16-1-2

LI-325C 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-325C is compliant with both RTCA DO-160, MIL-STD 461, CISPR 25, and CISPR 16-1-2.
The LISN provides defined stable impedance and isolates the EUT from power source influences, providing accurate and repeatable results.
The LI-325C 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-325C pair can accommodate 3-phase power systems (Wye or Delta configurations).
This LISN uses air-core inductors to prevent saturation and permeability variation.
The mounting plate of the LI-325C is left unpainted to facilitate connection to earth ground in its installation, which is essential due to the high leakage current.
All Com-Power LISNs are individually calibrated in compliance with the relevant requirements of RTCA DO-160, MIL-STD 461, CISPR 25 & CISPR 16-1-2. Impedance and Insertion Loss data are supplied with each unit, along with the calibration certificate.
