112255.305.NC | POWER SUPPLY FOR OPERATION OF THE NVR WITH A LOW VOLTAGE POWER SOURCE

Ajax

The Ajax 12V PSU for NVR, 112255.305.NC, is a power supply module designed to enable the operation of Ajax network video recorders on low-voltage power , ensuring continuous recording even in the event of a blackout or unstable power grid. Installed directly inside the NVR, it replaces the standard power supply and allows the use of batteries or alternative DC sources . It supports two operating modes, 8–16 V and 12.1–16 V , and offers protection against deep discharge thanks to automatic shutdown below the threshold. The solution ensures quick installation , stable and safe operation , and full compatibility with Ajax 8- and 16-channel NVRs , making it ideal for professional, highly reliable installations.

Main specifications:

- Low voltage power supply for Ajax NVR

- Continuous video recording even in the absence of a power supply

- Dual operating mode 8–16V and 12.1–16V

- Deep discharge protection with automatic shutdown

- Quick internal installation in the NVR compartment

- Compatibility with Ajax 8 and 16-channel NVRs

Further details

✅ Input without jumper installed:
In this configuration, the module operates with input voltage between 8 and 16 V DC , allowing the Ajax NVR to operate directly on low voltage sources without additional limitations, ideal for systems powered by batteries or stable DC lines.
✅ Input with a jumper installed:
With the jumper on , the input is set to 12.1–16V DC , a mode designed to protect the battery from deep discharge , as the NVR automatically shuts down when the voltage drops below 10.35V , ensuring greater safety and longer power supply life.
✅ Exit:
The module provides a stable nominal output of 12 V ±3% , ensuring continuous and reliable power supply to the network video recorder even under variable load conditions, with optimized power management and protection of the internal electronics.
✅ Installation:
Designed for direct internal installation in the NVR compartment , it replaces the standard power supply and allows quick assembly in about 10 minutes using common tools, making the operation simple even in professional contexts .
✅ Power connection:
Connection is via a standard power connector with DC jack and included clamp adapter , ensuring compatibility with various low voltage power sources and maximum flexibility of integration into systems.
