3 Phase LISN - For Medical Devices


9 kHz to 30 MHz


Three Phase LISN for CISPR / ANSI

The LI-3P-2x Series consists of four separate models of fourconductor, 50Ω, 50/250 µH +5Ω Line Impedance Stabilization Networks (LISNs); also known as Artificial Mains V-Networks (V-AMNs). The primary differences between the four models are their respective current ratings:

LI-3P-216 16 Amps (per line, continuous)
LI-3P-232 32 Amps (per line, continuous)
LI-3P-263 63 Amps (per line, continuous)
LI-3P-2100 100 Amps (per line, continuous)

These LISNs provide the necessary measurement platform for performing power line conducted emissions compliance testing per most worldwide commercial EMI/ EMC requirements, such as FCC (U.S.), CE (Europe), AS/NZS (Australia/New Zealand), VCCI (Japan), Industry Canada, etc.

Three phase LISNs

can be operated remotely or locally. Remote switching of the line under test (L1, L2, L3, N) is performed using the RLI-100 Remote LISN Interface, which controls the LISN via fiber optic connection.
In addition to the remote method, the line under test can also be selected using the mechanical, four-position switch located on the front panel of the LISNs. Using either switching method, the lines which are not selected are internally terminated into 50 ohms, while the selected line is terminated by the 50 ohm input impedance of the measuring instrument.
