At warehouse

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 trailer

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 yacht

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.


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.


12V PSU is installed into the device body, replacing the pre-installed 110/230 V power supply unit.
