Vad menas med en galvanisk avskiljare? Och hur funkar en sådan? Ger den märkbar bättre ljud?

(Har sett ett störningsfilter med galvanisk avskiljare för lågnivå som man kan köpa)

Tack för mig, over and out!

En søgning på Google gav følgende svar:

GALVANIC ISOLATIONA
Characteristic of a UPS or TRANSFORMER in which the output is completely electrically disconnected from the input. Power is coupled from input to output by magnetic fields in a TRANSFORMER within the UPS. A galvanically isolated output is considered to be a SEPARATELY DERIVED SOURCE according to the US National Electrical Code and is required to be grounded, that is, the output grounding wire must
be directly bonded to the input grounding wire. It is commonly but falsely believed that galvanic isolation eliminates GROUND LOOPs.

Med andre ord - en skilletrafo - 230 Volt ind og 230 Volt ud.

Jeg har i flere år med godt resultat anvendt en 3000 VA skilletrafo fra Lübke. Vægt 30 kg. Lyden bliver mere rolg og alle nettrafoer holder om med at snerre.

Mvh.
