Schwarzbeck NNLK 8129

A V-LISN from the NNLK series is required to measure conducted interference voltages according to VDE, CISPR, and related standards. It provides the device under test with a mains connection that has a standardized impedance of 50 Ω || 50 µH and reduces interference voltages coming from the mains. The interference voltage of the device under test is decoupled via a 7 kHz high-pass filter to the EMI measurement receiver.
