Re[2]: Line Filter for main power

Original poster: Illicium Verum <sebas@xxxxxxxxxxxxxxxx>


Hello Dirk,

Basicly yes. The one I toulk out of a powerbar had a nice inductor, some capacitors, automatic fuse and MOV. The netfilters you buy are housed in a metal case to prevent EMF from entering the filter, therefore I would recomend to buy one, but you can allways house it yourself in a metal case. But then again you might spend some time on it. It's all up to you ;)
