手段からなることを特徴とする負荷制御装置。[Scope of claim for utility model registration] The power supply voltage level is set to the first reference level and the second reference level.
Level discrimination means whose discrimination level switches when the power supply voltage changes across both the first and second reference levels, and detects that the discrimination level of the level discrimination means has switched. and a control means that outputs a load start/stop control signal after performing processing in accordance with power supply fluctuations, and inputs a discrimination signal of the level discrimination means and a control signal of the control means, and inputs a discrimination signal of the level discrimination means and a control signal of the control means. A load control device comprising a determining means for controlling start/stop of the load based on signal logic.
