PROBLEM TO BE SOLVED: To make an unmanned operation possible by using a generator for one power supply out of a plurality of power supplies and a commercial power supply for the other one and incorporating a UPS operation instruction communication means which receives a UPS operation instruction from remote places. SOLUTION: When a commercial power supply is stopped by a power failure while a computer 1 is working, a UPS 2 supplies uninterruptive power to the computer 1 and the computer 1 obtains the information about the power failure of the commercial power supply 5 from a commercial power supply power failure communication means 11 and then a power selection instruction communication means 13 sends out to a switch 3 an instruction to select a generator as a power supply. Furthermore, the UPS 2 has a built-in UPS operation command communication means 21 which receives a UPS operation command from a remote equipment 6 and drives an inverter 22 and a converter 24 to supply power to the computer 1. By this method, a computer power system controlling system can be started up from a remote place and an unmanned operation can be possible. |
