L1-500, L3-500
500A

Single line or Three-phase plus neutral 9 kHz – 30 MHz

The L1-500 and the L3-500 are fully compliant to:

  • CISPR 16-1-2
  • VDE 0876
  • FCC part 15
  • MIL-STD 461F

Description

Tailored for single-phase operations, the L1-500 stands out as a robust Line Impedance Stabilization Network (LISN), capable of managing a remarkable 500 amperes. This robust capacity renders it ideal for evaluating equipment with substantial current requirements.

The L3-500: Aggregating Four L1-500 Units for Three-Phase Assessments

Illustrated in the accompanying image, the L3-500 comprises four individual L1-500 units seamlessly integrated within a mobile rack. This amalgamation transforms it into a potent three-line V-network, perfectly suited for navigating conducted emissions testing in three-phase AC power environments.

Technical Insights and Operational Features

Equipped with an equivalent circuit of 50 ohms // (5 ohms + 50 microhenries), the L3-500 excels at pinpointing conducted emissions across the frequency spectrum from 9 kHz to 30 MHz. In essence, it efficiently identifies and analyzes unwanted electrical disruptions emanating from equipment within this targeted frequency range.

Affordable and Flexible Testing Solutions

Engineered with a focus on cost-effectiveness and versatility, both the L1-500 and L3-500 offer budget-conscious testing alternatives without compromising on performance. Their adaptability extends to a wide array of EMI receivers and spectrum analyzers, affording users the flexibility to tailor their testing setups to suit specific requirements.
