Com-Power LI-4100 LISN 100Amps (AC)-70Amps(DC), 10KHz-10MHz for MIL-STD 461.

The LI-4100 Line Impedance Stabilization Network can handle upto 100 Amps AC (70Amps DC) current and provides the necessary measurement platform for performing power line conducted emissions compliance testing as required by MIL-STD 461F.

The concept and advantages of the LISN is to:

a) connect in series with, and impose a defined impedance on, the lines under test; thereby providing a distinct advantage over current or voltage probe measurements, where the impedance of the lines is largely uncontrolled;

b) provide a coaxial RF measurement port for connection to the measurement equipment, to which the disturbance voltages present at the EUT port are coupled for measurement; and,

c) isolate the AE (ancilliary equipment) port from the EUT and RF ports, which:

1) minimizes the influence of the AE-connected equipment/cabling on the impedance (and voltage division factor) of the network; and,

2) reduces the amplitude of any ambient signals, as well as spurious disturbance voltages generated by the AE-connected equipment, thereby minimizing their potential impact on the measurement results.

Two pairs of LI-4100 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, also the 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.
