<P>PROBLEM TO BE SOLVED: To provide a power supply device which can control start or stop of power output to a load apparatus connected with a second output terminal while interlocking with turn on/off of a load apparatus connected with a first output terminal, and can suppress a rush current flowing into the power supply device, and to provide an uninterrptible power supply device and a power output control method. <P>SOLUTION: A current detecting section 16 detects the magnitude of a current delivered from an output terminal OT1 through a switch 17. Upon elapsing a predetermined delay time after the magnitude of a current delivered from the output terminal OT1 reached a predetermined threshold, a CPU 19 turns a switch 18 on to start power output from an output terminal OT2, and stops power output from the output terminal OT2 when the magnitude of a current delivered from the output terminal OT1 is under the predetermined threshold. The invention is applicable to an uninterrptible power supply. <P>COPYRIGHT: (C)2007,JPO&INPIT |
