Description 

The LI-220C Line Impedance Stabilization Network (LISN) is in full compliance with both CISPR 16-1-2 and ANSI C63.4. It provides the necessary measurement platform for performing power line conducted emissions compliance testing as required by most worldwide standards for commercial products.

This LISN uses air-core inductors to prevent saturation and permeability variation. The mounting plate of the LI-220C is left unpainted in order to facilitate connection to earth ground in its installation, which is essential due to high leakage current.

 Versatility

 The LI-220C 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 on the right, the LI-220C can be installed into any type of power system, including DC, single-phase, dual-phase and even three-phase systems.

Transient Protection

Com-Power Transient Limiters are a recommended accessory in order to protect the RF input of your measuring instrument from potentially damaging, instantaneous 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 filter sections which further attenuate any out-of-band emissions.

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.
