If you made a simple voltage divider that would give you around 12VDc from the 148VDC power plant you could use a circuit like this to watch the voltage change:

You'd have to do some experimenting. 73, Joe, K1ike skipp025 wrote: >> Chuck Kimball <n0...@...> wrote: >> Yes, trying to monitor the local -48 Power system, and >> solar charging system with my APRS digi +12VDC that accepts >> 0-5VDC input. >> Chuck >> > > The next part is how much resolution and accuracy do you want? > > There are a number of ways to fudge fixed step reporting but > a truly isolated circuit with scaled voltage tracking is > a more detailed animal. > > s. > > > > > ------------------------------------ > > > > Yahoo!
