The DC 2 will be integrated between your wall outlet and power distribution system, or you can connect appropriate devices directly.
DC components in our power supply are increasingly interfering with the operation of mains transformers. The physical principle of a transformer is the conversion of a voltage with the help of a magnetized ferrite core. But that only works with AC voltage. The unusable DC voltage leads to the hum of the transformer. At the same time, the transformer loses its resilience to a great extent. Our DC ﬁlters remove the DC voltage components reliably.
