    ac to regulated dc help

    MikeMI I built the circuit as specified (except C8 is 35V for now) and it gives me a 3.6Vdc out which I ran for about 6hrs with no problems. I am guessing to increase Vdc out I need to lower the resistance. Thanks again it seems to be exactly what I needed.

    ac to regulated dc help

    MikeMI This is the device I am using to aquire the signal. As you will see it does have optically isolated inputs. ControlByWeb: Five-Input Module Overview As you stated I would have (5) 24-29Vac sources with 1 common ground. Would it be to much to ask if you could draw me up a circuit...

    ac to regulated dc help

    tcmtech I am just trying to get a signal so I know what the air handler is doing(ie. is it in heat or cool or 1st stage compressor ect.) the 29Vac is going to relay's for each instance (W, Y1, Y2, R, O) so I am pulling a signal from across the 24Vac relay I have 17 units to monitor with 5...

    ac to regulated dc help

    Problem: I have a (5) 29Vac power signals from a air handler that I need to monitor with a device that can handle 3-12 Vdc and would like to keep the components down to a low cost low form factor. First circuit idea that was given to me was a 1N4001 diode in series with a 100uF capacitor...
