Ubiquiti UACC-ADAPTER-POE-24-12W 12W PoE Injector
Overview
The Ubiquiti UACC-ADAPTER-POE-24-12W is a compact 12W PoE injector that delivers 24V DC power and full data bandwidth over a single 2.5 GbE RJ45 connection. Designed to power Ubiquiti UniFi, UISP, and AmpliFi devices, this adapter injects power on pins 4, 5 (positive) and pins 3, 6, 7, 8 (negative), preserving all 2.5 Gbps of data throughput on the same cable run. The combination of modest power delivery and high-speed data support makes it a practical fit for distributed antenna systems, wireless bridges, and managed switches where a separate power supply would complicate installation.
Global AC input acceptance (100–240V) eliminates the need for regional voltage adapters in multi-site deployments. The integrated LAN activity indicator and reset button provide field visibility without requiring a laptop or management console, speeding troubleshooting in remote or hard-to-access locations.
Key Features
- 24V DC Output at 0.5A (12W): Delivers modest but reliable power for remote access points, managed switches, and PoE-enabled antennas. At 12W, it sits below the typical power ceiling of most cabinet-mounted switches, reducing the risk of power-budget exhaustion across large multi-device deployments.
- 2.5 GbE RJ45 Connection: Supports full-speed data while injecting power on the same cable. No separate power conductor needed, keeping cable runs simpler and reducing panel real estate.
- High Efficiency (82.96%): Low thermal waste means cooler operation in enclosed cabinets and extended power supply lifespan — relevant when ambient temperature or airflow is constrained.
- Surge & Transient Protection: Rated for 1500A (8/20 µs) discharge and 36A (10/1000 µs) peak pulse current on data lines. ESD/EMP protection at 6KV/10KV protects against incidental static discharge and nearby lightning, reducing downtime from transient faults in mixed indoor/outdoor cable runs.
- Over-Current Protection (0.6–1A): Automatic shutdown on short circuit or device overcurrent prevents cascading failures when a connected device draws excessive current.
- Output Ripple ≤1%: Clean DC output minimizes noise-related digital errors in sensitive analog circuits (audio, RF measurement) within connected devices.
- Wide Operating Temperature (0–40°C): Supports standard indoor and climate-controlled outdoor installations. Storage rating to –30°C allows safe shipping and warehouse staging in cold climates.
- Multi-Certification Compliance: CE, FCC, IC, UL, PSE, BSMI marks confirm electromagnetic compliance and electrical safety across North America, Europe, and Asia-Pacific regions. NDAA compliance eliminates sourcing restrictions for federal, state, and defense-adjacent deployments.
Integration & Compatibility
The UACC-ADAPTER-POE-24-12W (often searched as UACC ADAPTER POE 24 12W) is purpose-built for Ubiquiti device families requiring 24V DC input via a 2-pair PoE architecture. Compatible with UniFi access points, managed switches, and remote radio units designed for this voltage and injection scheme. Remote reset capability via a physical button allows you to remotely power-cycle a connected device without a site visit or management interface, useful for field recovery in locations where console access is impractical.
RJ45 shielded socket design reduces susceptibility to EMI in environments with heavy RF activity or nearby AC power infrastructure. When integrating into existing Ubiquiti IP camera or network switch deployments, verify that your target device explicitly lists 24V 2-pair PoE support; devices designed for 48V PoE or single-pair architectures will not function safely with this injector.
Frequently Asked Questions
Q: Can the UACC-ADAPTER-POE-24-12W power a standard PoE camera or access point rated for 802.3af (48V 15W)?
A: No. The injector delivers 24V DC, not 48V. Only use it with Ubiquiti devices explicitly rated for 24V 2-pair PoE input. Applying 24V to a 48V device will damage it; applying 48V equipment to this injector risks fire or equipment failure.
Q: What is the maximum cable run distance with the UACC-ADAPTER-POE-24-12W?
A: At 0.5A output, voltage drop depends on cable gauge and total run length. Standard Cat5e/Cat6 up to 100 meters (328 feet) is typical, but high-resistance runs or thin gauge will cause more drop. Test in your environment or consult the Ubiquiti device's DC input specification for acceptable voltage window.
Q: Is the UACC-ADAPTER-POE-24-12W suitable for outdoor or harsh-temperature deployments?
A: Operating temperature range is 0–40°C (32–104°F), suitable for indoor and controlled outdoor cabinets. Unheated or unshaded environments below 0°C or above 40°C are outside spec and may cause shutdown or damage. Enclosures or heater/cooler modules are required for extreme conditions.
Q: Does the injector work with non-Ubiquiti devices?
A: The UACC-ADAPTER-POE-24-12W is designed for Ubiquiti ecosystem devices only. Third-party equipment using different voltage specs or PoE architectures may not be compatible. Verify explicit support before deploying with non-Ubiquiti hardware.
Q: What certifications does the UACC-ADAPTER-POE-24-12W carry?
A: CE, FCC, IC, UL, PSE, and BSMI. It is also NDAA Section 889 compliant, making it suitable for federal, state, and defense contractor procurement.
Q: Is there a power cord included, or must I source one separately?
A: Package contents are not specified in available documentation. Contact the manufacturer or specialty distributor to confirm whether a power cord is included or must be purchased separately.

The UACC-ADAPTER-POE-24-12W is a straight-forward, low-power PoE injector purpose-built for Ubiquiti remote devices. At 12W and 24V, it sits in a narrow but important niche: powering managed switches, wireless bridges, and access points in distributed antenna or campus mesh topologies where a bulky PSU or multiple power cables would add complexity or cost. The 2.5 GbE pass-through is honest — you get full bandwidth alongside power on a single run.
Technical Highlights:
- 24V DC @ 0.5A (12W) Output: Modest power delivery by modern standards, but adequate for the Ubiquiti device family it targets. At 82.96% efficiency, waste heat is low, critical in sealed cabinets or stacked PoE installations where thermal budgets are tight.
- Surge/ESD Protection (1500A / 6KV): Real-world benefit: protects your switch or AP against incidental transient events (nearby lightning, static discharge from hot-swap cables). The 1% output ripple also keeps sensitive analog or RF circuitry in connected devices stable and noise-free.
- NDAA / Multi-Region Certification: CE, FCC, IC, UL, PSE, BSMI eliminates compliance friction across North America, Europe, and APAC. If you're bidding federal or state contracts, the NDAA mark is non-negotiable; this unit carries it.
Deployment Considerations:
- Voltage drop on long cable runs (beyond 100m) or thin gauge wire will reduce voltage at the device. Always verify your connected device's minimum DC input specification and test in situ if the run exceeds 50 meters.
- This injector is Ubiquiti-ecosystem only. If you're mixing third-party access points or switches into a UniFi infrastructure, confirm 24V 2-pair PoE compatibility before purchase — standard 48V PoE equipment will not work and risks fire hazard.
- Operating range 0–40°C is indoor/controlled outdoor only. Skip this if you need remote mountings in unheated enclosures or direct sun exposure in hot climates.
Use the UACC-ADAPTER-POE-24-12W when you're consolidating power distribution in a UniFi campus mesh or managed switch topology and want to avoid running separate 24V PSUs to each node. For single-building or indoor-only deployments with modest device density, it cuts clutter and reduces power supply failure points.
