About Power Supplies

Campbell Scientific's data acquisition systems are powered by reliable, inexpensive 12 Vdc sources. Power consumption by our dataloggers, peripherals, and sensors is minimal, allowing extended operation from our standard sealed rechargeable battery or set of alkaline cells. Systems that require more power can be supplemented with external rechargeable batteries, regulators, and charging sources (ac power or solar panels).

FAQs for

How can it be determined which power supply is the best for a system?

Estimating the power consumption of a system can help with selecting the best power supply option. The system's power consumption can be approximated by calculating the average current required by the datalogger, sensors, and peripheral equipment. This average current drain is primarily determined by the percentage of time spent in an "active" versus "quiescent" state, which can be approximated from the datalogger's scan rate and program length.

For more information, and guidance through the calculations, see our power supply overview or application note.

Can a motorcycle battery be used to power a system?

Yes. However, if the datalogger's battery is rechargeable, disconnect the datalogger's battery when using the motorcycle battery. Two rechargeable batteries that have different Ahr ratings should not be connected in parallel.
