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.
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.
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.
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 Plus||GSM||35 mA|
|Hub 2||GSM||33 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).
|Compatibility||Hub, Hub Plus, ReX|
|Input voltage||8-20 V DC|
|Output voltage||4.65 V ± 3%|
|Switch-on voltage||8 V ± 2.5%|
