3 Phase - Line Impedance Stabilization Network

  • 3 Phase LISN for CISPR / ANSI The LI-3P-1x series consists of four separate models of four-conductor, 50Ω / 50 μH Line Impedance Stabilization Networks (LISNs).
  • The primary differences between the four models are their respective current ratings: LI-3P-116 16 Amps (per line, continuous) LI-3P-132 32 Amps (per line, continuous) LI-3P-163 63 Amps (per line, continuous) LI-3P-1100 100 Amps (per line, continuous) The side panels for each LISN are louvered for cooling purposes.
  • The LI-3P-163 and LI-3P-1100 also include two internal cooling fans operated by a switch on the rear panel.
  • 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 that are not selected are internally terminated into 50 ohms, while the selected line is terminated by the 50-ohm impedance of the measuring instrument.
  • Frequency Range: 150 kHz to 30 MHz
  • Current Ratings of 16, 32, 63 and 100 Amps
  • Fully Compliant with CISPR 16-1-2/ANSI C63.4
  • Remote Switching of Line Under Test
  • Four-conductor, 50Ω / 50 μH Networks appropriate for both 3Ø Delta and Wye Power Configurations
  • Three-Year Warranty
