Com-Power LI-400C 10 kHz - 10 MHz LISN for Mil-STD 461

Introducing the LI-400C Line Impedance Stabilization Network (LISN): Precise Compliance Testing for Power Line Conducted Emissions

The LI-400C Line Impedance Stabilization Network (LISN) stands as the essential cornerstone for conducting power line conducted emissions compliance testing, a requirement stipulated by the majority of global standards governing commercial products. Furthermore, the LI-400C is fully compliant with MIL-STD 461, demonstrating its versatility and adaptability for diverse testing scenarios.

At its core, the LISN furnishes a meticulously crafted measurement platform that bestows stable impedance characteristics, while effectively isolating the Equipment Under Test (EUT) from extraneous power source influences. This isolation is pivotal in ensuring the precision and repeatability of testing outcomes. The LI-400C includes a pair of single-conductor networks, individually housed, to be seamlessly integrated in series with each current-carrying conductor within single-phase, dual-phase, or DC power systems. For the convenience of users grappling with 3-phase power systems, be it in Wye or Delta configurations, a second LI-400C pair can be employed.

The LI-400C boasts shrouded sockets at the mains (power input) and EUT (power output) ports, providing an intuitive and secure connection process. To further simplify setup, matching color-coded plugs designed for mains and EUT wiring are thoughtfully included.

What sets the LI-400C apart is its utilization of air-core inductors. This design choice is deliberate, intended to avert saturation and permeability variations, ensuring consistent and accurate results. Notably, the mounting plate of the LI-400C is intentionally left unpainted, a critical detail facilitating a secure connection to earth ground. This precautionary measure is paramount, especially considering the potential for high leakage current in such testing environments.

For those seeking to optimize their testing setup, it is highly advisable to incorporate a Transient Limiter. This addition not only aids in impedance matching but also serves to reduce out-of-band emissions and provides essential transient protection for your measurement instruments. Com-Power offers this invaluable accessory to enhance the efficacy of your testing apparatus.
