<P>PROBLEM TO BE SOLVED: To provide a power system which performs the break of a plurality of power voltages to a load within a predetermined time, according to its order, when power input is cut off or when breaking a power source. <P>SOLUTION: A power unit 100 converts a voltage input from a power source 10 into an intermediate voltage. A power unit 200 receives the input of the intermediate voltage output by the power unit 100 and outputs a plurality of voltages converted and generated therein. A sequence controller 400 detects the drop of the voltage input from a power unit 10 and performs the break control on the power voltage by the power unit 200 within a predetermined time, according to a predetermined order. A power unit 110 converts the voltage input from the power source 10 into a power voltage to operate the sequence controller 400. <P>COPYRIGHT: (C)2009,JPO&INPIT |
