摘要： The present invention includes plural power supplying units, a power distributing backplane and more than one protection circuits, wherein the power supplying unit produces an output power and the power distributing backplane integrates the output powers from plural power supplying units and distributes thereof into plural driving powers for supplying loads. The power circuit for the driving power to drive each load has a protection circuit mounted thereon, wherein the protection circuit detects a driving condition of the load or the power circuit, and according thereto, the protection circuit becomes open or close so as to disconnect or maintain the driving power. Therefore, the abnormal driving power will not influence the operation of the whole power system and other normal loads still can maintain operation. Furthermore, since plural power supplying units are used to provide the power needed by loads, the power capacity will not be wasted.
