12V PSU for Ajax NVR, Low-Voltage Power Supply Board
SKU AJ-112255
- Fast shipping from four branches
- 30-day returns on unopened products
A power supply board that lets an Ajax NVR run from a low-voltage source rather than the mains. It is the part that makes a recorder viable in a cabinet fed from a central DC supply or a backed-up low-voltage rail.
Built for the installer
On a commercial install where everything else in the rack is already on a supervised DC supply with battery backup, running the NVR from a separate mains adapter is the weak link. This removes it.
It is a board-level part fitted to the recorder, IP20, with a 24-month warranty.
Key features
- Runs the NVR from a low-voltage source instead of a separate mains adapter
- Puts the recorder on the same backed-up supply as the rest of the rack
- Board-level fitment, no external enclosure
- 24-month warranty

FAQs
What problem does this solve?
It lets the NVR run from a low-voltage source rather than its own mains adapter, so the recorder can sit on the same supervised, battery-backed supply as the rest of the rack.
Which recorder does it fit?
The Ajax NVR. Confirm the available low-voltage supply meets the unit's requirement before installing.
Does this device need an Ajax hub?
Yes. All Jeweller devices report to an Ajax hub or a range extender. The device cannot operate standalone and does not connect to a third-party panel directly.
What does the 9NA region code mean?
It is the North America model, operating on the 905.0-926.5 MHz Jeweller band certified to UL/ULC standards. European 868 MHz models are not interchangeable with it.
