This site had one 12V power supply for all systems:
EVE & sensors, CO2 pumps, valves and CO2 data system.
Since we're seeing low voltage at the campbell boxes (11.2V) at this
site (and site 8) we'll try adding a power supply and see if that
helps the soil profiles.
A white 4x8x3 inch power supply (5A?), is in a cooler at
the mast along with a battery.
EVE, power supply and the battery are all wired in
parallel, using a multi-branch power cable.
An extension cord runs back to the chem shelter.
We're using the outlet on the transformer that the chem shelter
air conditioner was on. The air conditioner is now off - Kurt
doesn't think it is necessary to cool the transformer.
Bring an outlet strip if you want to power up the AC.
This switch was possible without powering down the CO2 system.
Finished at about 18:00 CDT.
We're now seeing 13.8V at EVE and 13.2 at the campbell boxes.
