Low voltage protection

In general, if the input voltage value of a load exceeds the specified level, the risk of failure increases due to overheating and other factors. However, if it is too low, there is also a risk of failure or malfunction. Therefore, measures against low voltage are necessary. This refers to a function that stops the operation of the power supply circuit or generates an alarm signal when the output or input voltage of the power supply circuit falls below the specified value. In power supply circuits and similar systems, a function that treats an input voltage below the specified value as an off state and prevents it from being accepted in order to guarantee the specified output is also one type of low voltage protection.
