10.5 Power Supplies
10.5.1 Overview
Power-supply systems may include batteries, charging regulators, and a primary
power source such as solar panels or ac/ac or ac/dc transformers attached to mains
power. All components may need to be checked if the power supply is not
functioning properly.
Diagnosis and Fix Procedures
(p. 435) includes the following flowcharts for
diagnosing or adjusting power equipment supplied by Campbell Scientific:
Battery-voltage test
Charging-circuit test (when using an unregulated solar panel)
Charging-circuit test (when using a transformer)
Adjusting charging circuit
If power supply components are working properly and the system has peripherals
with high current drain, such as a satellite transmitter, verify that the power supply
is designed to provide adequate power. Information on power supplies available
from Campbell Scientific can be obtained at www.campbellsci.com. Basic
information is available in the appendix Power Supplies
(p. 564).
