Ubiquiti UACC-PSU-12V-550W Hot-Swappable Power Module
Overview
The UACC-PSU-12V-550W is a replacement hot-swappable power supply module engineered for Ubiquiti network video recorders, CloudKey Enterprise, and Enterprise Aggregation systems. This 550W module delivers 12V DC at 45A and accepts universal AC input (100–240V, 50/60 Hz), enabling technicians to replace failed or degraded supplies during live operation without system shutdown. Hot-swap capability is a practical advantage in 24/7 surveillance deployments where downtime directly impacts security coverage.
Key Features
- 550W Output (12V DC, 45A): Sufficient headroom for multi-channel NVR systems with attached storage and network infrastructure. At 45A continuous, this module can sustain full-load recording and PoE switch operation simultaneously without thermal throttling or performance loss.
- Hot-Swap Design: Live replacement without requiring system power-down. Technicians can pull the failed UACC-PSU-12V-550W unit and insert a fresh module in seconds, keeping recording and network connectivity intact. Critical for sites where interruption breaches SLA or compliance windows.
- Universal AC Input (100–240V, 50/60 Hz): Operates across North American, European, and Asian grid standards without manual voltage selection. C14 connector is industry-standard IEC, so existing power distribution infrastructure integrates without adapters.
- Compact Form Factor (185 x 73.5 x 40 mm): Fits standard 1RU and 2RU rackmount configurations with minimal thermal bypass. Weight of 744 grams keeps mounting stress low and simplifies field transport and replacement labor.
- SGCC Steel Enclosure: Mild-steel construction with galvanized finish resists corrosion in humid or marine-adjacent deployments. Not military-grade armor, but adequate for indoor data-center and telecom-closet environments.
- NDAA Compliant, FCC/CE/IC Certified: Meets U.S. government procurement restrictions and international safety standards. If your organization operates under federal security guidelines or exports surveillance systems, NDAA compliance eliminates a procurement gate. Certifications confirm safe thermal behavior and electromagnetic compatibility in shared rack space.
Integration & Compatibility
Direct replacement for Ubiquiti CloudKey Enterprise, Enterprise Aggregation, and Enterprise NVR systems. Confirm your host system model before ordering — this module is not compatible with consumer-grade UniFi Protect or legacy Ubiquiti recorders. Installation requires no firmware update or configuration; simply extract the old module, align the connector, and slide the new UACC-PSU-12V-550W unit into the hot-swap bay until it seats and locks.
If deploying across multiple NVR sites, consider redundant power supply modules as a backup stock. Carrying one spare UACC-PSU-12V-550W in your field kit costs little and eliminates wait time for overnight shipping if a unit fails during an active deployment.
When to Choose a Different Module
If your Ubiquiti installation uses older CloudKey or non-Enterprise NVR hardware, verify compatibility with your equipment documentation. Ubiquiti offers alternative power modules for legacy systems; contact your vendor or consult the host system manual for the correct part number. If your system requires redundant N+1 power architecture, confirm that your NVR chassis supports dual power-module configuration before ordering multiple UACC-PSU-12V-550W units.
Frequently Asked Questions
Q: Can I hot-swap the UACC-PSU-12V-550W while the NVR is recording?
A: Yes. The hot-swap design allows live replacement. Power and recording continue uninterrupted as long as the system has not completely lost power. If both power modules are pulled simultaneously, the NVR will shut down. Avoid that scenario in production.
Q: What is the warranty on this power module?
A: Warranty information is not specified in the available documentation. Contact your vendor for coverage terms and return procedures.
Q: Is the UACC-PSU-12V-550W NDAA Section 889 compliant?
A: Yes, the module carries NDAA compliance marking, which satisfies federal procurement restrictions on certain Chinese-origin components. Verify that your complete system (NVR, modules, and peripherals) meets your organization's supply-chain security policy, as NDAA applies to individual components.
Q: Can I use this power module with non-Ubiquiti NVR systems?
A: No. The UACC-PSU-12V-550W is engineered specifically for Ubiquiti CloudKey Enterprise, Enterprise Aggregation, and Enterprise NVR platforms. Other brands' systems have proprietary connectors and voltage rails. Using it on incompatible hardware will damage the NVR or power module.
Q: What is the input connector type?
A: Standard C14 IEC connector. This is the three-hole female receptacle found on most rackmount power distribution units and modular UPS systems.
Q: Does this module support redundant or N+1 power configuration?
A: If your Ubiquiti NVR chassis has dual power-module slots, yes, you can install two UACC-PSU-12V-550W units for failover redundancy. Consult your NVR manual to confirm slot availability and failover behavior.

The UACC-PSU-12V-550W solves a real operational pain point: unplanned power-module failure in a live 24/7 recording system. A failed PSU means a dead NVR, which means blind spots on your coverage — and in regulated environments, that's a compliance violation. The hot-swap architecture eliminates the need for a full system power-down during replacement, which matters most in mission-critical deployments where even brief interruptions trigger incident reports.
Technical Highlights:
- 550W continuous at 45A: Sufficient for multi-channel recording, onboard storage controllers, and integrated PoE power distribution without derating. You won't hit thermal limits under sustained load.
- Universal AC input (100–240V, 50/60 Hz): Eliminates region-specific SKUs. Deploy the same module across North America, Europe, and Asia without rewiring or voltage concerns.
- NDAA compliance: If your organization has federal procurement gates, this module passes the restricted-components screen. Not every accessory carries this marking, so verify your baseline security policy before assuming other Ubiquiti accessories meet the same standard.
Deployment Considerations:
- Verify chassis compatibility: This module is purpose-built for CloudKey Enterprise, Enterprise Aggregation, and Enterprise NVR systems. Older CloudKey or non-Enterprise hardware uses different power connectors. Check your NVR manual's power-module compatibility matrix before purchasing. A wiring mistake here wastes a day and damages expensive equipment.
- Single point of failure in single-PSU chassis: If your NVR has only one power-module slot, the UACC-PSU-12V-550W is your only power source. No redundancy. If your uptime SLA requires N+1 power, confirm your chassis supports dual-slot configuration before assuming you can add a second module later.
- Field replacement logistics: Keep one spare in your mobile kit. PSU failures are unpredictable and often happen outside business hours. A spare module costs roughly $300–400 and eliminates overnight shipping delays on active incidents.
Deploy this module as a direct replacement or stock spare for any CloudKey Enterprise or Ubiquiti Enterprise NVR installation. In hybrid environments where you're mixing Ubiquiti and third-party systems, confirm each system's power-module standard before bulk ordering. The UACC-PSU-12V-550W shines in centralized NVR rooms where live hot-swap capability avoids scheduling maintenance windows — a real operational advantage over cold-start replacements.
