The LISNs are intended for EMI conducted emissions testing. The LISN model LI-400 is placed between the
power source and the EUT (Equipment
Under Test) to stabilize line impedance,
provide a 50 ohm RF connection, and
block unwanted RF noise from the
external power source. The LI-400 uses air coils in the current path in
order to avoid saturation due to high current. This model can handle up to 25 A of current. It was designed to test products according to Mil-std 461 standard..
The model LI-400 has separate
enclosure for each LISN network and are shipped in pairs for single phase
testing. Additional networks can be purchased separately for testing
more than one phase. They have Superior Electric sockets for power connection.
