The L3-32 from Narda Safety Test Solutions is a Line Impedance Stabilization Network (LISN) with a frequency range from 9 kHz to 30 MHz. It has a continuous output current of up to 32 A and an in-built, selectable 150 kHz high-pass filter. It is equipped with a 250 µH choke and a 50 µH choke, which are connected in series for each path. This LISN meets the requirements of CISPR 16-1-2, VDE 0876, FCC Part 15, and MIL-STD 461F, and is backed by local and remote control from PMM EMI receivers. It features robust and stable mechanical construction, high-quality electric components, easy and perfect grounding, and solid input-output power connections. It uses a 50-ohm BNC female output, 32 A IEC, and 16 A SCHUKO connectors. It is available in an enclosure that measures 342 x 254 x 510 mm and requires an AC supply. 

The L3-32 provides a repeatable, accurate measurement of the disturbance voltage that EUT (equipment under test) may inject into the power mains. It is suitable for measurement on AC 3-phase power circuits from DC to 60 Hz.
