3 Phase LISN - For Medical Devices
- 3 Phase LISN for CISPR / ANSI The LI-3P-2X series consists of four separate models of four-conductor, 50Ω / 50 μH Line Impedance Stabilization Networks (LISNs). LI-3P-2X series Frequency Range is 9 kHz to 30 MHz
- 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) The side panels for each LISN are louvered for cooling purposes.
- The LI-3P-263 and LI-3P-2100 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.
