Abstract

An external and redundant power device provides external electric powers and redundant electric powers. The external and redundant power device includes power supply units, a power integrated circuit, a power output control circuit and a controller. The power supply units provide input power streams. The power integrated circuit further integrates the input power to a whole power supply and converts a whole power supply first part into a first power. The power output control circuit acquires the whole power supply and respectively output preset power streams to the power receiving devices. The controller controls the power output control circuit outputting the preset power streams according to a whole power supply status and a connection condition.
