LISN
Line Impedance Stabilization Networks (LISN) are essential tools for conducted emissions testing, providing a defined line impedance for the device under test (DUT). By isolating the DUT from external noise on the power lines, they ensure repeatable and accurate measurements during electromagnetic interference (EMI) evaluations. The series supports both pre-compliance and full compliance testing across various industrial, commercial, and automotive standards. The construction of these units focuses on precision and high-power handling, utilizing high-quality components to maintain stable impedance characteristics across wide frequency bands. Models like the L1-150M offer switchable operations to accommodate different standards such as ISO 11452-4 and CISPR 25. High-current versions are specifically engineered to handle up to 500 A, making them suitable for testing heavy industrial equipment and large-scale power systems. The range includes diverse models from compact 8 A units to robust 3-phase 100 A and 500 A networks with 690 Vac ratings. Specialized accessories like the TBLM2 LISN Mate for common mode and differential mode separation and the TBGP-250 roll-up ground plane are available to further enhance laboratory setups. Whether for single-line DC testing or complex four-line 3-phase AC measurements, this portfolio provides a comprehensive solution for modern EMC testing requirements.Wide Frequency Coverage
