Ajax 12-24V PSU (Type A) Low-Voltage Power Supply for Hub 2/Hub 2 Plus/ReX 2

Ajax 12-24V PSU (Type A) - Low-Voltage Power Supply for Hub 2, Hub 2 Plus & ReX 2

The Ajax 12-24V PSU (Type A) is an alternative internal power board that lets a compatible Ajax hub or range extender run from a low-voltage DC source instead of the standard mains supply. Fitted inside the device enclosure in place of the bundled 110/230V power unit, it opens up reliable Ajax protection for vehicles, vessels, and sites where mains electricity is unstable or simply unavailable.

Key Features

• Wide input range: Accepts an 8-32V DC power source, covering both 12V and 24V systems.
• Vehicle and marine ready: Suited to car and truck batteries, portable power packs, and onboard boat or yacht electrical systems.
• Simple internal fit: Swaps directly into the hub or range extender enclosure in place of the pre-installed mains board, using just a screwdriver.
• Flexible wiring options: Includes a standard power jack connection plus a bundled terminal adapter for direct wire hookup.
• Compact and lightweight: A small board designed to sit neatly inside the existing device housing without altering its footprint.
• Stable regulated output: Delivers consistent power to the hub or range extender electronics even as input voltage fluctuates.
• Broad device compatibility: Works with Hub 2, Hub 2 Plus, and ReX 2 range extenders.
• Professional-grade reliability: Backed by Ajax's manufacturing quality and compliance testing for security alarm equipment.

Keeping Ajax Protection Running Anywhere

This power board is designed for scenarios where a fixed mains connection isn't practical. Installers can use it to keep a caravan, boat, cargo trailer, remote warehouse, or work vehicle protected around the clock by tapping into an existing 12V or 24V battery or low-voltage supply. Because it fits inside the same enclosure as the original power unit, the swap is quick and does not affect the way the hub or range extender otherwise operates within an Ajax security system.
