12-24V PSU (type A): New alternative power supply unit suitable for trucks

We’re introducing 12-24V PSU (type A), the updated version of an alternative power supply unit for connecting an Ajax hub or range extender to an 8-32 V⎓ power supply. The new model replaces the previous, 12V PSU for Hub 2/ReX 2.

It comes with new packaging, including an image of the new PSU, new naming, and the input voltage range. The device is already available for order from Ajax Systems partners.

What’s new

The main difference between models is compatibility with Hub (4G) Jeweller and Hub 2 Plus Jeweller control panels, ReX 2 Jeweller radio signal range extender, and the ability to work with an input voltage of up to 32 V⎓. This significantly expands the capabilities of security and installation companies. Ajax systems can now protect trucks and vans with their cabs and cargo beds inside.

Why use 12-24V PSU (type A)

There are two reasons:

The premisest has no or unstable power supply: empty buildings, “mothballed” summer cottages, construction sites, or warehouses.
The property does not provide 100–230 V~ power supply: vans, trucks, camper trailers, or yachts.

With 12-24V PSU (type A), a hub or radio signal range extender can be connected to a portable battery, car battery, uninterruptible power supply (with a backup battery), or even to an in-vehicle network.

When not connected to the 100–230 V~ mains Ajax hubs operate for up to 16 hours, and range extenders for up to 38 hours on a built-in backup battery. 12-24V PSU (type A) is installed inside the device enclosure instead of the standard 110–230 V~ power supply unit. A setup with 12-24V PSU (type A) and an uninterruptible power supply with a 9 A·h battery will run autonomously for over a week.

Read Portugalenses Transportes' customer story as an example of the non-standard use of Ajax PSU: by integrating alternative power supply units, the company protected its trucks from fuel theft.

The Ajax product portfolio also includes 6V PSU (type A) for connection to the 4.2–10 V⎓ portable battery.

What about the previous PSU model

We are no longer producing and shipping 12V PSU for Hub 2/ReX 2. Technical support and warranty service remain valid.

Instead of the previous model, order a new 12-24V PSU (type A) from official Ajax Systems partners. The product comes with new packaging so that users and partners can easily distinguish the latest model from the previous one.
