Overview
Com-Power LIN-120C Line Impedance Stabilization Network
150 kHz to 30 MHz, FCC/EN/CISPR, multiline LISN, 20 A, 50 uH
- Provides a defined, stable impedance across the measurement frequency range;
- Isolates the EUT and measurement circuit from the power source, thereby minimizing its influence on the measurements; and,
- Couples the disturbance voltages to the coaxial measurement port (either directly, or through a transient limiter w/10 dB attenuation, depending on switch position), for connection to the measuring instrument.
This LISN uses air-core inductors to prevent saturation and permeability variation. Its mounting plate is left unpainted in order to facilitate connection to earth ground in its installation, which is essential due to high leakage current
Versatility
The LIN-120C is a dual-conductor network capable of handling currents up to 20 Amps(AC) per line. The EUT power port is fitted with a universal, multi-configuration receptacle, which accomodates almost any EUT plug without the need for adapters. The power input port is fitted with a standard IEC C20 receptacle.
As shown in the diagrams, the LIN-120C can be installed into any type of power system, including DC, single-phase, dual-phase and even three-phase systems.
Transient Protection
The LIN-120C is equipped with a built-in transient limiter to protect the RF input of your measuring instrument from potentially damaging voltage transients. The transient limiter also reduces the possibility of overload by incorporating two 5 dB attenuation/impedance matching pads, in addition to its low-pass and high-pass filters which further attenuate out-of-band emissions. When the Transient Limiter ON/OFF switch is on the “OFF” position, the transient limiter circuit, including the 10 dB of attenuation and band-pass filters are bypassed.
Calibration
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 certificate of calibration. Recognized ISO 17025 accredited calibration is also available upon request.
