<p><P>PROBLEM TO BE SOLVED: To provide effective power supply backup of the entire in-house by accommodating power between respective uninterrupted power supply management devices in in-house environment in which a plurality of uninterrupted power supply management devices exit. <P>SOLUTION: In an in-house environment with a plurality of UPSs 2 (uninterrupted power system), power is accommodated to each other between the respective UPSs 2 to thereby achieve effective power backup of the entire in-house. Namely, a UPS in which battery capacity sufficiently remains supplies battery power to the other UPS whose battery capacity is deficient when AC power supply is abnormal, and a UPS in which battery capacity sufficiently remains supplies battery power to the other UPS whose battery capacity is deficient when the AC power supply is restored. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
