1 Amp Fuse
Voltage
The sonde is designed to run with 12-volt batteries, with
supply voltages between 9 and 16 V DC.
These systems
should be directly powered by a sealed battery or installed
as part of a remote solar system.
Power the SOA through a
1-amp slow-blow fuse for protection. Remove the fuse until
all wiring is completed.
When used with a solar system always ensure use of
12-volt solar regulator. Never connect the sonde directly to
solar panel; voltages above 16.5 volts will cause the sonde to
shut down and excessive voltage will permanently damage
the sonde and is not covered under warranty.
