<p><P>PROBLEM TO BE SOLVED: To obtain a power controller ensuring suitable power supply by controlling power consumption. <P>SOLUTION: When any one of a plurality of electric apparatuses 2 connected with a power controller 1 is started or the electric energy being supplied to any one electric apparatus 2 is switched, and a predetermined power is supplied to that electric apparatus 2 by originating a request signal from the electric apparatus 2 to the power controller 1, whether an allowable electric energy assigned to the power controller 1 is exceeded or not is decided and starting the electric apparatus 2 or switching electric energy thereof is permitted within a range of allowable electric energy. Since a power (current) above the allowable electric energy does not flow through the power line, superfluous power supply is not performed and a plurality of electric apparatuses 2 can be operated in safety. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
