Com-Power LI-220C 20 Amps LISN for CISPR 16 & ANSI C63.4
I Introducing Com-Power LI-220C:
LISN 9 kHz to 30 MHz 250 & 50 µH Inductor LI-220C Line Impedance Stabilization Network (LISN) provides the measurement platform necessary to perform emissions compliance testing performed on power lines in accordance with requirements of most standards worldwide for commercial products. The LI-220C complies with both CISPR 16-1-2 and ANSI C63.4. LISN provides stable, defined impedance and isolates the EUT from power influences, thereby providing accurate and repeatable results. The LI-220C consists of a pair of single conductor networks, placed together, installed in series with each conductor carrying current in a single-phase, two-phase or DC electrical system. The second pair of LI-220Cs can be used to supply a 3-phase power system (Wye or Delta configuration). This LISN uses an air core inductor to prevent saturation and permeability variations. The mounting plate of the LI-220C is unpainted to facilitate connection to ground during installation, which is essential due to the high leakage current. The use of Transient Limiters for impedance matching, reducing out-of-band emissions, and transient protection of your measurement equipment is recommended and is available from Com-Power. All Com-Power LISNs are individually calibrated to the relevant requirements of CISPR 16-1-2 and ANSI C63.4. Impedance, Phase, Isolation and Insertion Loss data are provided with each device, along with a certificate of calibration.
