For AC input SSR
For example, when the input voltage range is 90~240v and the input return voltage is 20v
Is there a problem that occurs when a value between 20v (return voltage) and 90v (minimum input voltage) is applied as an input voltage?

Most of the uses of AC SSR are commercial power sources. However, since the voltage range used around the world is 90~240V, the input voltage range is written as 90~240V, and in reality, it can operate even if it is 20~30V or more.
That is, if the input return voltage is 20V, it can be considered that it operates normally when it is higher than 20V.
