Due to its construction as well as to the software controlling it, the
power consumption is extremely low. The unit operates off an internal
6.2 volt rechargeable battery, which is charged either by a solar panel
or an external power adapter. A special configuration can be
implemented where an external 12 volt (rechargeable) battery can be
used in addition to or instead of the internal rechargeable batteries.
The external rechargeable battery will not be recharged by the RA440.
The RA440 is a ruggedized unit, complying with the IP65
environmental protection class (NEMA 4). You can easily install and
integrate the unit into an Adcon A733 network. Depending on the
topography, you can get a reliable wireless connection to an A733
series device up to 20 km (12 mi.) away. Under favorable conditions,
the distance can be even farther. You should be aware that the RA440
operates within the GSM/GPRS network coverage provided by your
local cellular provider.
