Information

This information is part of the Modelica Standard Library maintained by the Modelica Association.

Connectors PositivePin and NegativePin are nearly identical. The only difference is that the icons are different in order to identify more easily the pins of a component. Usually, connector PositivePin is used for the positive and connector NegativePin for the negative pin of an electrical component.

Connector Variables (1)

v	Causality: None Type: ElectricPotential (V) Description: Potential at the pin

Flow Variables (1)

i	Type: Current (A) Description: Current flowing into the pin
