Description
Ajax 12v PSU for Hub, Hub Plus & Rex
A power supply unit used for connecting the Hub, Hub Plus control panels and ReX radio signal range extender to low-volgate power sources.
In Warehouses:
Use Ajax in premises lacking electricity or having an unstable power supply. A 12 V power supply unit allows connecting hubs and radio signal extenders to low-voltage networks or use a portable battery.
In Campervans and Caravans:
Ajax protects your home, even if it goes on wheels. Connect the hub to a car or portable battery, and let the security system travel with you.
On Yachts:
Insert a SIM card and connect the hub to the on-board network or battery so that Ajax always guards your boat at the pier.
Compatibility:
The power supply unit is compatible with Hub, Hub Plus, and ReX. It features a standard socket for connecting the power jack plug and has a bundled terminal adapter.
Installation:
12V PSU is installed into the device body, replacing the pre-installed 110/230 V power supply unit.

Calculate Power Consumption
How to calculate the time of operation of the central panel from an external battery:
Divide the capacity of the external battery by the power consumption of the central panel.
Power consumption of the central panel depends mostly on active communication modules — the average values are indicated in the table:
Central panel | Active communication modules | Average input current |
Hub | GSM | 42 mA |
Ethernet | 80 mA | |
GSM+Ethernet | 90 mA | |
Hub Plus | GSM | 35 mA |
Ethernet | 72 mA | |
GSM+Ethernet | 93 mA | |
Wi-Fi | 20 mA | |
Wi-Fi+GSM | 42 mA | |
Wi-Fi+Ethernet | 80 mA | |
Wi-Fi+GSM+Ethernet | 96 mA | |
Hub 2 | GSM | 33 mA |
Ethernet | 80 mA | |
GSM+Ethernet | 86 mA | |
ReX | — | 20 mA |
For instance, when connected to a 40A·h battery, Hub 2 — with active GSM module only — will operate approximately 1200 hours (40A·h / 0.033A).
