3.1
Power supply source
The Cairnet use a battery which allows it to be fully autonomous 3 to 6 days (Depend of the embedded sensors types
and of the carrier network quality too).
The battery is a LI-ION battery [3.7V/19 200 mAh with short-circuit and overvoltage protection included].
The power connector, accessible from the bottom of the box, must be connect to a power supply source (outdoor
main power supply or solar panels optional) or indoor main power supply provided with the Cairnet.
Depending on the use, 2 types of power supply source can be used:
Operating mode
Solar Panel
Power supply
Indoor or
outdoor
2 X 13.5W _ VCO = 10.5V / ICC = 1,6 A
Optimal conditions
115-230VAC _ 50-60Hz / 7 to 12 VDC _1 .5A
Overload protection and overvoltage
Connector type and polarity
Mechanical size
ᴓ hole ᴓ central core
5.7 mm
2 mm
The user must ensure that the power supply is always active and functional.
The Solar Panel requires a maintenance by cleaning of the active surface with a soft and wet cloth. The period of the
maintenance is to be defined by the end user depending the use conditions.
