Com-Power is a specialist manufacturer of EMC and RF test equipment, providing solutions for electromagnetic compatibility testing, emissions measurement and immunity testing. Its portfolio includes antennas, signal generators, EMI receivers, amplifiers, LISNs, field probes and EMC test software. Trusted by engineers in electronics, automotive, aerospace and compliance laboratories, Com-Power products support accurate EMC testing and compliance with international standards.
The LI-400C Line Impedance Stabilisation Network provides the necessary measurement platform for performing power line conducted emissions compliance testing as required by most worldwide standards for commercial products.
The LI-400C is compliant with 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-400C 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-400C pair can be used to accommodate 3-phase power systems (Wye or Delta configurations).
The LI-400C 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-400C 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 Com- Power.
All Com-Power LISNs are individually calibrated in compliance with the relevant requirements of MIL-STD 461. Impedance and Insertion Loss data is supplied with each unit, along with the calibration certificate.
