Overview
Com-Power LI-3P-2X Series Includes:
- Mating Socket Connector for Power Input Cable
- Mating Plug Connector for EUT Power Cable
- RLI-100 Remote LISN Interface
- Fiber Optic Cable (30 meters)
- AC Power Adapter (6 VDC, 500 mA, unregulated)
- AC Power Adapter (15 VDC, 500 mA, unregulated)
The LI-3P-2X series LISN's uses 50uH or 250uH air-core inductors to prevent saturation and permeability variation. The mounting plates are left unpainted in order to facilitate connection to earth ground in their installation, which is essential due to high leakage currents.
Com-Power LI-3P-2X Series Features:
These LISN's provides the necessary measurement platform for performing power line conducted emissions compliance testing as required by CISPR 16-1-2 and ANSI C63.4 .international EMC test standard requirements for commercial products. The LISN will perform each of the following functions during the measurement:
- provide a defined, stable impedance across the measurement frequency range;
- isolate the EUT and measurement circuit from the power source, thereby minimizing its influence on the measurements; and,
- couple the disturbance voltages to the coaxial measurement port, which connects to the measuring instrument.
Remote or Local Operation:
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.
