Abstract

The invention relates to a pseudo isolated power conditioner, like a common mode inductor (1), or system with similar function, for field bus systems. The common mode inductor (1) or system with similar function, sited upstream of each participating segment (3) power conditioner (2), is utilized to provide, or assist, adequate segment (3) impedance and/or cross talk and/or adequate high frequency interference attenuation on and/or between participating segments (3), where participating segments (3) comprise adequate power conditioning (2) with each participating segment (3) unbalance within the constraints outlined within IEC61158-2.
