About Charging Sources
Charging sources offered by Campbell Scientific include solar panels and ac chargers and transformers. The charging source powers the system while float-charging the rechargeable batteries. The batteries then provide back-up power if the charging source is interrupted.
A regulator must be used to connect rechargeable batteries with a charging source. The regulator controls the current flowing to the battery and prevents the battery current from flowing to the charging source. Some of our solar panels contain a regulator integrated into their cable.
Please note that the rechargeable batteries contained in our CR3000 and CR5000 dataloggers may also be recharged via vehicle power. To do this, a DCDC18R Boost Regulator is required (refer to the Regulator Section for more information).
