Main Features
• 9 kHz to 30 MHz frequency range
• Up to 300 A (continuous); 500 A (20 min.)
rated output current
• Suitable for DC to 60 Hz power lines
• Built-in, selectable 250 µH coil (Choke)
• Meets the requirements of several standards
including CISPR 16-1-2, VDE 0876, FCC part

• Stackable in up to four units in wheeled rack
(see data sheet L3-500)
The AMN - Artificial Mains Network, also known as LISN - Line Impedance Stabilization
Network - is the ancillary 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.
L1-500 is suitable for measurement on power circuits from DC to 60 Hz.
The equivalent V-Network circuit of 50 Ω // (5 Ω + 50 μH) with 250 μH 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.
