This will provide battery backup to the alarm system. In case of power failure your digital display will stay on and read current temperature in the box. This way the min/max memory will still be working and your alarms will still flash and buzz once the temperature is in alarm state. Your backup system will also have two notification lights, one will blink when it is in power failure mode and the second will blink when you need to replace the battery. The battery is a 12 volt rechargeable battery.
This will not power the refrigeration system.
