L3-32 3-phase LISN

Product catalog summary
Overview: The L3-32 is an Artificial Mains Network (AMN), also known as a Line Impedance Stabilization Network (LISN), designed for accurate measurement of disturbance voltage from Equipment Under Test (EUT) into power lines. It ensures repeatable measurements by providing a known impedance and phase response across the test frequency range.
Specifications:
  • Frequency Range: 9 kHz to 30 MHz
  • Max Continuous Rated Output Current: 32 A
  • Max Operating Voltage: 230 VAC; 325 VDC for single-phase, 400 VAC; 565 VDC for three-phase
  • Input Mains Frequency Range: DC to 60 Hz
  • Equivalent Circuit: 50 Ω // [5 Ω + 50 µH] with 250µH choke
  • RF Output: BNC female
  • Rated Temperature: -10 °C to +40 °C
  • Storage Temperature: -25 °C to +75 °C
  • Dimensions: 342 x 254 x 510 mm
  • Weight: 16.5 kg
Main Features:
  • Powering the EUT with standardized impedance
  • Coupling and decoupling of measuring receiver to/from disturbance signals
  • Built-in selectable 150 kHz high pass filter
  • Artificial Hand circuit
  • Local and remote control compatibility with PMM EMI receivers
  • Compliance with standards such as CISPR 16-1-2, VDE 0876, FCC part 15, MIL-STD 461F
Installation Requirements:
  • Properly rated insulating transformers are required between mains power line and AMN line inputs for electrical safety and ground protection.
  • High mains noise may necessitate the use of mains filters to reduce unwanted signals.
Related Products:
  • Various EMI receivers and RFI filters compatible with the L3-32
  • Optional LISN service kit for verification and calibration
Ordering Information: The L3-32 package includes an IEC mains plug, RF cable, LISN remote control cable, user’s manual, and calibration certificate.

L3-32 3-phase LISN-1

Three phase plus neutral V-Network 9 kHz - 30 MHz, 32 A for AC and DC powered EUT Provided Features • • • • Main Features Powering the EUT EUT termination to a standardized impedance respect to the reference ground Coupling the measuring receiver to the disturbance generated by the EUT Decoupling the measuring receiver from unwanted RF signals from the power line • 9 kHz to 30 MHz frequency range • Up to 32A continuous rated output current • Built-in, selectable 150 kHz high pass filter • Artificial Hand circuit • Suitable for DC to 60 Hz power lines • Local and remote control from PMM EMI receivers • Meets the requirements of several standards including CISPR 16-1-2, VDE 0876, FCC part 15, MIL-STD 461F The AMN - Artificial Mains Network, also known as LISN - Line Impedance Stabilization Network - is the ancilliary device intended for repeatable and accurate measurement of the disturbance voltage that an EUT (Equipment Under Test) may inject into the power line or mains. This is obtained by providing well known impedance value and phase response across the frequency range of the test. L3-32 is suitable for measurement on AC 3-phase power circuits from DC to 60 Hz. The equivalent V-Network circuit of 50 Ω // (5 Ω + 50 μH) with 250μH choke is fully compliant with the reference standards. PMM Artificial Mains Networks provide robust and stable mechanical construction, high quality electric components, easy and perfect grounding, solid input-output power connections. They can be used in conjunction with any EMI receiver or spectrum analyzer and offer features required for safe, repeatable and accurate measurements.
