See
CR200(X) Power Supply
(p. 53).
The CR200(X) operates from a DC power supply with voltage ranging from 7 to
16 V, and is internally protected against accidental polarity reversal. The
CR200(X) has modest input power requirements, typically an average current
drain of less than 3 mA. Models with built-in radios may have a higher average
current drain, depending on the radio’s power mode and amount of time the
radio is in use. Be sure to include the current usage of the radio and any
powered sensors when calculating power supply requirements.
In low power applications, the CR200(X) can operate for several months on
non-rechargeable batteries. Power systems for longer-term remote applications
typically consist of a charging source, a charge controller, and a rechargeable
battery. When AC line power is available, an AC/DC wall adapter and a
rechargeable battery can be used to construct a UPS (uninterruptible power
supply) in conjunction with the CR200(X)'s built-in voltage regulator/charge
controller. Contact a Campbell Scientific applications engineer for assistance in
acquiring the items necessary to construct a UPS.
Applications requiring higher current requirements, such as satellite or cellular
phone communications, should be evaluated by means of a power budget with a
knowledge of the factors required by a robust power system. Contact a
Campbell Scientific applications engineer if assistance is required in evaluating
power supply requirements.
Common power devices are:
•
Batteries
•
Alkaline D-cell - 1.5 V/cell
•
Rechargeable Lead-Acid battery
•
Charge Sources
•
Solar Panels
•
Wind Generators
•
AC/DC wall adapters
