12V PSU for NVR
Power supply unit for the device operation on a low-voltage power source
Uninterrupted recording in a power outage
12V PSU for NVR is an electronic board that is installed into the video recorder enclosure, replacing the standard 110/230 V~ power supply unit. With the alternative power supply unit, an Ajax NVR can operate on a low-voltage power source instead of the facility’s power grid. This setup ensures continuous video recording, making it ideal for protecting property with unstable or no power supply.
Hassle-free installation
A professional electrician can install the alternative power supply unit into a network video recorder in just about 10 minutes, using a single PH1 screwdriver and the device manual.
12V PSU for NVR supports two operating modes:
8-16 V
In this mode, an Ajax video recorder operates within the 8-16 V voltage range. A jumper should not be installed.
- 12V PSU for NVR is installed directly inside the NVR enclosure, replacing the standard 110/230 V power supply unit.
- A standard jack plug is used to connect the power cable.
A terminal adapter is included in the complete set.
12.1-16 V
This mode allows an Ajax video recorder to operate on a voltage that exceeds 12 V. To prevent a full discharge of the power supply, the NVR automatically switches off if the voltage drops below 10.35 V. A jumper must be installed.
