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.

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 panelActive communication modulesAverage input current
HubGSM42 mA
Ethernet80 mA
GSM+Ethernet90 mA
Hub PlusGSM35 mA
Ethernet72 mA
GSM+Ethernet93 mA
Wi-Fi20 mA
Wi-Fi+GSM42 mA
Wi-Fi+Ethernet80 mA
Wi-Fi+GSM+Ethernet96 mA
Hub 2GSM33 mA
Ethernet80 mA
GSM+Ethernet86 mA
ReX20 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).
