The EM-7823 Line Impedance Stabilization Network (sometimes referred to as a “V Network”) is a two line low pass filter network designed to isolate an electrically operated device from an external power source (usually the power mains). It provides a stable and consistent line impedance at the frequencies where radio interference measurements are made.

The 50 µH / 250 µH network implemented in this LISN may be used in making high frequency conducted measurements according to most commercial test specifications including ANSI and certain FCC, CISPR and VDE tests. It features a current carrying capacity of 15 Amperes.

Power input and output connections are made using standard power mains plugs and sockets. The user may choose from many available styles including European (Schuko), French, U.K., Australian, Japanese and U.S. (NEMA) style connections.
