LI-550A Com-Power LISN


The LI-550A is a new LISN from Com-Power. A line impedance stabilization network (LISN) device is something engineers use to test radiofrequency (RF) emission and susceptibility. During an electronic equipment test, engineers place the LISN device between an alternating current or direct current power source and the equipment under test.

The Com-Power LI-550A 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 Com-power LI-550A is compliant with both CISPR 25 and CISPR 16-1-2.

The Com-Power LI-550A 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-550A pair can be used to accommodate 3-phase power systems (Wye or Delta configurations).
