Overview
The Com-Power LI-3P-263 LISN provides the necessary measurement platform for performing power line conducted emissions compliance testing as required by most worldwide standards 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.
The LI-3P-263 LISN uses 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. The side panels for the LISN are louvered for cooling purposes.
