The LI-215A 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-215A 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-215A 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-215A pair can be used to accommodate 3-phase power systems (Wye or Delta configurations). The LI-215A is equipped with IEC connector at the mains (power input) and NEMA 5-15R at EUT (power output) ports. This LISN uses air-core inductors to prevent saturation and permeability variation.
The mounting plate of the LI-215A is left unpainted in order to facilitate connection to earth ground in its installation, which is essential due to high leakage current. Use of a Transient Limiter for impedance matching, reduction of out-of-band emissions and transient protection for your measurement instrument is highly recommended and available from Dynamic Sciences. All Dynamic Sciences 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 is supplied with each unit, along with the calibration certificate.
