12V PSU for NVR
Overview
The 12V PSU for NVR is a low‑voltage power module that replaces the standard 110/230 V AC supply inside an Ajax network video recorder. It enables the NVR to operate from an 8–16 V DC source, ensuring continuous video recording in locations with unstable or unavailable mains power.
Key Features
- Operates from 8–16 V DC (no jumper) or 12.1–16 V DC (with jumper)
- Maximum current consumption up to 4 A
- Output current up to 2 A
- Turn‑on/turn‑off voltage thresholds for stable operation
- 12 V DC ±3% regulated output
- Shutdown current 110 μA; quiescent current 65 mA
- Installs inside the NVR enclosure in place of the bundled PSU
- Operating temperature 0 °C to +40 °C
- Operating humidity up to 75%
- IP20 protection class
- Connector options: 6.5 × 2.0 mm (female), 5.5 × 2.1 mm (male)
- Cable support: AWG 12–14
- Dimensions: 118 × 123 × 17 mm
- Weight: 51 g
Ideal Applications
- Off‑grid or backup‑powered surveillance systems
- Remote sites with unreliable mains supply
- NVR installations requiring DC power integration
- Environments where uninterrupted recording is critical
Security & Durability
The module provides stable regulated output, safe voltage thresholds, and low‑power standby behaviour. Proper installation inside the NVR enclosure ensures electrical safety and long‑term reliability under professional surveillance workloads.
