摘要

The power bus (1) has a current source (3) for controlling a supply voltage control circuit (4), where the current source for multiple fault-current-controlled loads (2) is arranged in a bus. The power bus is formed as a ring separated by a switch (5). The supply voltage control circuit (4) is switched by the switch of the current source on both open ends (7,9) of the power bus.
