Abstract
A state of a plurality of switches for performing application and cutoff of a plurality of electrical loads is stored in a memory circuit. A pattern of supply power after application of the load for each of the plurality of electrical loads and a load response priority order assigned previously to each of the electrical loads are stored in a memory table. A control circuit identifies a newly applied load on the basis of the turned-on state of the plurality of switches stored in the memory circuit and instructs an electric power supply circuit to supply electric power in accordance with the supply power pattern corresponding to the identified load, while the control circuit prohibits application of the newly applied electrical load when an electrical load having the load response priority order higher than that of the newly applied electrical load has been already applied. The memory table may store consumption power and an application priority order assigned previously to each of the electrical loads. In this case, a total amount of consumption power of the applied electrical loads is calculated. When an electrical load having the application priority order lower than that of the newly applied electrical load has been already applied and the control circuit judges that the total amount of consumption power of the applied electrical loads exceeds a predetermined value, the control circuit instructs to cut off the electrical load having the lower application priority order.
