Detection delay function

The detection delay function of voltage detector is a function that does not output a detection signal immediately after the monitoring voltage reaches the detect voltage, but outputs it after a certain period of time has passed.

This delay time is called detect delay time. There are few voltage detectors equipped with detection delay function. For the voltage detector equipped with this function, the delay time can be externally adjusted using an external capacitor.

The voltage of monitoring line may instantaneously drop at startup of power supply or due to inrush current when the motor operates. The output of wrong detection signal is prevented by using the detection delay function when the voltage detector unintentionally outputs a detection signal due to this instantaneous drop of power supply voltage.
