低下を夫々検出し少′なくとも１つに検出出力が得られ
るときにコンピュータをロック状態にするリセット信号
出力を得る瞬時電圧低下検出回路手段と、この手段より
も遅れて各電源の出力電圧低下を夫々検出しこの検′出
出力が一定時間継続したときに各電源個別に異常表示さ
せかつ他の電源も含めて電源しゃ断する電圧低下検出回
路手段とを備えたことを特徴とするコンピュータ用直流
電源の監視装置。a first DC power supply used as a logic power supply for a computer;
In a DC power supply for a computer having a second DC power supply serving as a power source for at least one of peripheral circuits and devices of the computer, in each power supply, an instantaneous drop in the output voltage of each power supply is detected respectively, and at least one is detected. An instantaneous voltage drop detection circuit means for outputting a reset signal that locks the computer when an output is obtained, and a voltage drop in the output voltage of each power supply is detected later than this means, and this detection output continues for a certain period of time. 1. A computer direct current power supply monitoring device comprising voltage drop detection circuit means for displaying an abnormality for each power supply individually and shutting off the power including other power supplies when a voltage drop occurs.
