Description
The LIN-115A 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 LIN-115A is compliant with both CISPR 16-1-2
and ANSI C63.4.
The LISN provides dened stable impedance and
isolates the EUT from power source inuences,
thereby providing accurate and repeatable results.
LIN-115A
impedance matching, reduction of out-of-band
emissions and transient protection for your
measurement instrument.
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 certicate.
Typical Connection Diagrams
The LIN-115A includes one pair of single-conductor
Single Phase connection with one set of LISN
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
LIN-115A pair can be used to accommodate 3-phase
power systems (Wye or Delta congurations).
The LIN-115A is equipped with IEC connector
at the mains (power input) and NEMA 5-15R at
EUT (power output) ports.
Three Phase connection with two sets of LISNs
This LISN uses air-core inductors to prevent
saturation and permeability variation. The
mounting plate of the LIN-115A is left unpainted in
order to facilitate connection to earth ground in its
installation, which is essential due to high leakage
current.
The LIN-115A has a built in transient limiter for
