Line Impedance Stabilization Network

LI-215A

Features

Frequency range of 9 kHz to 30 MHz

Fully compliant with CISPR 16-1-2 / ANSI C63.4

“Air-core” inductors to prevent saturation

Individual Calibration Included

Three-Year Warranty

The LI-215A 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-215A is compliant with both CISPR 16-1-2 and

ANSI C63.4.

The LISN provides dened stable impedance and

isolates the EUT from power source inuences,

thereby providing accurate and repeatable results.

The LI-215A includes one pair of single-conductor

networks, housed together, to be installed in series

with each current-carrying conductor in a single-

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

LI-215A pair can be used to accommodate 3-phase

power systems (Wye or Delta congurations).

The LI-215A is equipped with IEC connector at

the mains (power input) and NEMA 5-15R at EUT

(power output) ports.

This LISN uses air-core inductors to prevent

saturation and permeability variation. The

mounting plate of the LI-215A 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

CISPR 16-1-2 and ANSI C63.4. Impedance, Phase,

Isolation, and Insertion Loss data is supplied with

each unit, along with the calibration certicate.
