Hello,
Me and my partner are working on a project with PIC micro controller. The project requires us to take a 500V pulse from a device and to read it with the PICs analog to digital converter. The problem we are having is that the 500V to 5V transformers we have found are either too expensive or unavailable.
Is there any suggestions here from people on how me and my partner can cost effectively isolate this 500V source safely from our PIC, perhaps using an opto isolator?. Also, the voltage we are trying to read is a very fast pulse, so that must be accounted for.
Thanks!
-Dave
