Line Impedance Stabilization Network

LI-400

Features

Frequency range of 10 kHz to 10 MHz

Fully compliant with MIL-STD 461

“Air-core” inductors to prevent saturation

Individual Calibration Included

Three-Year Warranty

The LI-400 Line Impedance Stabilization Network

(LISN) provides the necessary measurement

platform for performing power line conducted

emissions compliance testing as required by most

worldwide standards for commercial products.

The LI-400 is compliant with MIL-STD 461.

The LISN provides dened stable impedance and

isolates the EUT from power source inuences,

thereby providing accurate and repeatable results.

The LI-400 includes one pair of, separately housed,

single-conductor networks, to be installed in series

with each current-carrying conductor in a single-

phase, dual-phase or DC power system. A second

LI-400 pair can be used to accommodate 3-phase

power systems (Wye or Delta congurations).

The LI-400 is equipped with Superior Electric

SUPERCON® shrouded sockets at the mains

(power input) and EUT (power output) ports. The

matching color-coded plugs for connection to the

mains and EUT wiring are included.

This LISN uses air-core inductors to prevent

saturation and permeability variation. The

mounting plate of the LI-400 is left unpainted in

order to facilitate connection to earth ground in its

installation, which is essential due to high leakage

current.

Use of a Transient Limiter for impedance matching,

reduction of out-of-band emissions and transient

protection for your measurement instrument is

highly recommended and available from Com-

Power.

All Com-Power LISNs are individually calibrated

in compliance with the relevant requirements of

MIL-STD 461. Impedance and Insertion Loss data is

supplied with each unit, along with the calibration

certicate.
