[GreenKeys] Loop supply options

[Ralph Mowery]

That might be something to think about.   I am not sure how much power the device could handle (dissipate)  before getting too hot.  Many of the 3 terminal regulators can only handle a few watts.  It probably would work if say a 1000 to 1500 ohm resistor was in series with it.

 

I had not looked at them in a long time and then they were only rated for  about  1 to 2 watts and under 40 volts.

 

Thanks.
