Overview
The ECCSS LISN 3 was developed following the "European Cooperation for Space Standardisation". The ECSS LISN 3 is used for DC mains lines. The red wing terminal must be connected to the positive voltage, the black terminal to the negative. The impedance characteristic of each path is basically realized by an inductor in parallel with the 50 Ohm resistor: 0.7 µH || 50 ?.
The device under test has to be connected to the terminals at the front panel. The supply voltage has to be connected at the back panel.
The device under test may drain a continuous current of 10 A and for a short period of time it may even drain more than 15 A.

Attention:
The built in capacitors are electrolytic so the correct polarity is a MUST!
