Com-Power LI-3100 LISN (100 Amps) for DO-160, MIL-STD 461 & CISPR 25/16
I Introducing Com-Power LI-3100:
DO-160, MIL-STD 461, CISPR 25 and CISPR 16
Model Line Impedance Stabilization Network (LISN): LI-3100 can handle current up to 100 Amps AC (70 Amps DC) and provides the measurement platform necessary to perform emissions compliance testing present on power lines as required by DO-160 & MIL-STD 461F and CISPR 25 and CISPR 16 from 10 kHz to 400 MHz.
The concept and advantages of LISN are:
a) connect in series and apply a specified impedance to the lines under test; thus providing a distinct advantage over current or voltage probe measurements, where line impedance is largely uncontrolled;
b) provide a coaxial RF measurement port for connection to measuring equipment into which the disturbance voltages present at the EUT port are coupled for measurement; And,
c) isolate the AE port (auxiliary equipment) from the EUT and RF ports, where:
1) minimize the influence of the AE connected device/cable on the impedance (and voltage division coefficient) of the network; And,
2) reduce the amplitude of any ambient signals as well as spurious noise voltages generated by the AE connection device, thereby minimizing their potential impact on the measurement results.
Two pairs of LI-3100s can be used to supply a 3-phase power system (Wye or Delta configuration).
