Abstract:
An electrical load controller that controls the starting sequence for a plurality of electrical loads includes a start demanding unit that generates a demand to start at least one of the plurality of electrical loads. A first electrical load is started immediately if the time between when a second electrical load start and when the second electrical load receives a signal indicating that the first electrical load will start (second prescribed time) is longer than the time required to send the signal between the first and second electrical loads (third prescribed time), and the time required for an inrush current to decrease to a prescribed value (first prescribed time) is less than the difference between the second prescribed time and the third prescribed time. Thus, there is sufficient time for the inrush current of the first electrical load to decrease before starting the second electrical load.
