Introduction：
The NNLK 8121 is a LISN Linear Impedance Stabilization Network manufactured by Schwarzbeck, Germany and authorized for sale by EUTTEST. The device under test must be connected to the wing terminals on the front panel of this LISN. The maximum current that can be passed through each path is 50 A, and the maximum operating voltage of the DUT is 250 VAC or 400 VDC. The circuit principle is designed with an impedance of (50 µH+5 Ω) || 50 Ω, and four butterfly screws are provided on both the front and rear panels for testers to use.

100A current option:
You can also use the 8121 LISN for current applications up to 100A. If you want to use more than 50A-100A regularly, please contact us for the high voltage high current option, then 100A can be used continuously.
