i have to controle a high voltage voltage of 360V and 430V
Does any one have a solution
i found a sensor of DC has maxi 25V very low voltage
Do you need to measure this DC voltage or is it necessary only to know if it is on or off ?
no , to know that the exactly output value
It may be that something like this could work with a suitable choice of resistors for the voltage divider: https://www.ti.com/lit/ds/symlink/amc1411-q1.pdf?ts=1650171985882
Extreme care is necessary with the voltages you are talking about which are well outside the normal scope of a hobby electronics project. Ensure any solution is adequately isolated from the voltage source you are measuring.
