Com-Power LI-125A LISN 150kHz-30MHz




The Com- Power LI-125A 150 kHz- 30 MHz Line Impedance Stabilization Network (LISN) is ideal for conducted emissions testing for EMC Pre-Compliance testing. In addition, all Com Power LISN’s are compliant to most worldwide standards such as FCC, CISPR, FAA and DOD.

The LI- 125A 30MHz LISN provides accurate and repeatable results by isolating the DUT from power source influences and providing defined stable impedance.

The Com-Power LI-125A LISN 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-125A LISN pair can be used to accommodate 3-phase power systems (Wye or Delta configurations). The matching color-coded plugs for connection to the mains and DUT wiring are included.

The mounting plate of the Com Power LI-125A is left unpainted in order to facilitate connection to earth ground in its installation, which is essential due to high leakage current. Please contact us for more information.
