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 defined stable impedance and
isolates the EUT from power source influences,
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 configurations).
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 certificate.
