50µH CISPR 16-1-2 LISNs



The NNLK 8121 is equipped with a 250 µH choke as well as with a 50 µH choke which is connected in series for each path. The 250 µH choke provides an excellent decoupling between the power supply and the device under test starting at 9 kHz.

Due to high capacities very high leakage currents can occur (above 1 A). Thus it is not possible to use a residual current operated circuit breaker. It is recommended to use an isolating transformer. The supply voltage has to be applied at the back panel of the LISN by using the wing terminals.

The device under test has to be connected to the wing terminals at the front panel. The maximum current that can be drawn is 50 A for each path. The maximum voltage that can be applied is 250 VAC or 350 VDC. For a short period of time 100 A may be drawn from the LISN. If you want to use more than 50 A regularly, consider buying the options “high current” and “fans”, then 100 A may be drawn continuously.

The input for the power supply is located at the back panel and provides wing terminals as well. The coaxial RF output has to be connected to the EMI measurement receiver using a BNC coaxial cable. You can choose the path that needs to be measured with the path selection switch. The paths that are actually not measured will be terminated with 50 Ω automatically.
