## Buildings.Electrical.DC.Interfaces

Package with interfaces for DC electrical systems

### Information

This package contains connectors that are used by the models in the Buildings.Electrical.DC package. The connectors extends the basic connectors Buildings.Electrical.Interfaces.Terminal and define a new graphical icon in order to be distinguished by connectors of other electrical systems (e.g. AC systems).

Extends from Modelica.Icons.InterfacesPackage (Icon for packages containing interfaces).
