Hello,
I would like to measure DC voltage up to 150V. It is easy to measure the DC voltage through resistive divider (see page 11 in https://tinycontrol.pl/media/documents/m...008_EN.pdf), but I do not know How to make a protection. Can you suggest me something which make the circuit safe from overvoltage ? Actually the primary circuit is protected by DC power surge protector DS240S-130DC from overvoltage so it may be sufficient, but I have no experience with that - is it needed/useful to have second protection ?
