<p>PURPOSE:To prevent an electrical load from lowering its function, by controlling the operation of the electrical load in accordance with the difference between the gross generation margin and the consumed current of the electrical load. CONSTITUTION:A condition detecting means 8 detects the rotational speed or temperature of an alternator 1 driven by an engine 7. Further, a means 10 for detecting a current consumed by an electrical load and an operation change-over means 5 connected to electrical loads 13 takes an output from a means 6 for judging the load condition of an electrical load, into a generation margin computing means 9. Further, the engine 7, the electrical load change-over means 5 and a display unit 12 are controlled in accordance with an output from the generation margin computing means 9.</p> |
