Com-Power LI-150A – Line Impedance Stabilization Network, LISN pair, 50 uH, 150 kHz to 30 MHz, 50 Amps, FCC/EN/CISPR

• 150 kHz to 30 MHz
• CISPR 16-1-2
• ANSI C63.4
• 50 microhenry
• 50 Amps

The LI-150A 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-150A 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-150A 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-150A pair can be used to accommodate 3-phase power systems (Wye or Delta configurations).

The LI-150A 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-150A 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.
