Section 6. CR200(X) Power Supply
Reliable power is the foundation of a reliable data acquisition system.
When
designing a power supply, consideration should be made regarding worst-case
power requirements and environmental extremes.
Contact Campbell Scientific if assistance in selecting a power supply is needed,
particularly with applications in extreme environments.
6.1 Power Requirement
The CR200(X) operates from a DC power supply with voltage ranging from 7 to
16 V. It is internally protected against accidental polarity reversal. Input
voltages in excess of 18 V may damage the CR200(X) and/or power supply.
Caution
The B and Battery - terminals on the wiring panel are
not regulated by the CR200(X); they obtain the same power directly the
POWER IN terminal. When using the CR200(X) wiring panel to source
power to other 12 V devices, be sure the power supply regulates the
voltage within a the range specified by the manufacturer of the
connected device.
6.2 Calculating Power Consumption
Read More! Power Requirements
(p. 29).
System operating time for batteries can be determined by dividing the battery
capacity (ampere-hours) by the average system current drain (amperes). The
CR200(X) typically has an average current drain of less than 3 mA. The duty
cycle of the radio will add to the current drain. Be sure to include the current
used by any powered sensors when calculating power supply requirements.
6.3 Power Supplies
APPENDIX. Power Supplies
p. 30 lists external power supplies available from
Campbell Scientific, including alkaline and solar options. Complete power
supply information is available in manual or brochure form at

.
6.3.1
Battery Connection
Any clean, 7 to 16 VDC supply may be connected to the B and Battery -
connector terminals on the front panel. When connecting external power to the
CR200(X), insert the positive lead into the B terminal. Insert the ground
lead into the Battery - terminal.
