According to the present invention, a power supplying device for an archive system, for example, uses a plurality of SMPS units with small capacity and properly provides direct current power with large capacity for the archive system. Therefore, there is no need to specially manufacture an SMPS unit with large capacity. Consequently, an increase of production costs of the archive system can be prevented. Moreover, only a current detection circuit from which over currents are detected is automatically cut so that the archive system can be protected from over currents and the direct current power can be properly supplied through an output terminal. Therefore, critical errors on the whole operations of the archive system are prevented from occurring in advance. |
