Backup Power Supply Connection
To avoid the tracker turning off, when the main power supply shuts down, the power supply
driver supports connection of a backup power supply.
Switching between the main power supply and the backup power supply is performed
automatically. If the main power supply turns off, the tracker switches to the backup power
supply. As soon as the main power supply is restored, the controller will switch back to the
main power supply.
The tracker can be setup to send a low voltage notification via SMS to a preset telephone
number, if the backup supply voltage falls below 11 V.
It should be note, that AutoGRAPH-GSM is not equipped with the battery charger. All other
modifications of AutoGRAPH controller have a built-in charger to charge connected back up
battery.
