<p><P>PROBLEM TO BE SOLVED: To provide a device that is an uninterruptible power supply device (UPS) which is provided with a backup power supply and has an adjustable reserve power level, based on user input. <P>SOLUTION: The UPS provides reserve power, and the reserve power is later utilized to reactivate the UPS, after a shutdown, that is when an inactive state occurs when a user demand for reserve power is received. The UPS utilizes a rechargeable battery that can supply stored AC power, when an AC power line input voltage level falls below a threshold level and a shutdown occurs. A user can adjust the reserve level, in proportion to the user input, and the user can later reactivate the UPS, in order to supply AC power stored for a prescribed period of time. According to one embodiment, the user can execute computer code on the user's computer so as to adjust by remote means the level which is at the reserve power level and based on a measurement value of the backup power available from the UPS. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
