PURPOSE:To provide a power supplying system for package which can minimize its power supply trouble when a power source module becomes faulty for communication equipment, etc., in which power is supplied to load circuits in a plurality of packages constituting a unit from power source modules respectively incorporated in the packages. CONSTITUTION:A power source module 11, power source fault detecting means 12 which detects the abnormal output voltage of the module 11, switching control means 13 which sends a switching control signal in accordance with information from the means 12, and switching means 14 which operates under the control of the control means 13 are incorporated in each package 10 and, when the module 11 becomes faulty, the detecting means 12 detects the abnormal output voltage of the module 11 and the switching means 14 operates under the control of the control means 13 which receives the fault information. As a result, electric power is supplied to a load from an emergency power source. |
