Com-Power LISN 50 Amps for DO-160 & MIL-STD 461 quality

I Introducing Com-Power LISN LI-350

LI-350 LISN for DO-160 & MIL-STD 461F, can handle current up to 50 Amps AC (35 Amps DC) and provides the measurement platform needed to perform conducted emissions compliance testing operate on power lines as required by DO-160 & MIL- STD 461F.

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-350s can be used to supply a 3-phase power system (Wye or Delta configuration).
