Ubiquiti POE-24-24W-G-WH PoE Adapter
Overview
The Ubiquiti POE-24-24W-G-WH is an external PoE injector designed to deliver 24 volts DC and data across a single Gigabit Ethernet connection. Built for the UISP ecosystem, this adapter injects power directly into the data line, eliminating the need for separate power supply runs to remote devices. The 24W budget supports low-power wireless radios, field devices, and distributed antenna system (DAS) components that operate on passive 24V PoE input.
The single Gigabit port (RJ-45) provides straightforward integration without requiring smart PoE switches or complex provisioning. The external form factor permits flexible placement in network closets, weatherproof enclosures, or wall-mounted configurations, making it practical for deployments where centralized power injection is impractical.
Key Features
- 24V DC Power Output: Delivers passive PoE at 24 volts—compatible with Ubiquiti UISP accessories and any 24V PoE-rated field device. Passive PoE avoids negotiation overhead, so power is delivered immediately upon connection with no handshake delay.
- 24W Power Budget: Sufficient for low-power IP radios, compact antennas, and sensor modules. Verify your target device's wattage requirement before deployment—exceeding 24W may cause the adapter to shut down or damage the device.
- Gigabit Ethernet Port: Single RJ-45 connector supports full 1 Gbps data throughput, ensuring no bottleneck between your network and the powered device. Standard Cat5e or Cat6 cabling works without modification.
- AC/DC Input: The adapter accepts either AC mains (wall outlet) or DC input, offering flexibility in environments where only one power source is available. Verify input voltage range and connector type against your local power supply before installation.
- Compact External Housing: Weighing 0.800 lb, the POE-24-24W-G-WH occupies minimal rack or shelf space. The external form factor dissipates heat naturally without fans, reducing maintenance and noise in sensitive environments.
- UISP System Integration: Purpose-built for Ubiquiti UISP devices and accessories, ensuring power and data compatibility without third-party adapter stacks or compatibility risks.
Integration and Deployment Scenarios
Deploy the POE-24-24W-G-WH in three primary scenarios:
- Wireless Radio Backhaul: Inject power to point-to-point or point-to-multipoint radios in tower-mounted or rooftop enclosures, eliminating long power cable runs from the main facility.
- Remote Sensor or Camera Clusters: Power compact UISP field sensors or low-power IP cameras in distributed warehouse, yard, or outdoor surveillance zones where PoE switch ports are unavailable or cost-prohibitive.
- Distributed Antenna Systems (DAS): Provide centralized power injection to remote antenna units in large facilities without requiring a dedicated UPS or conditioning unit at each antenna location.
In all cases, verify that the powered device is rated for passive 24V PoE input. Smart devices expecting 802.3af (48V) or 802.3at (48V high-power) negotiation will not function with this adapter.
Compatibility and Planning Considerations
The POE-24-24W-G-WH is designed exclusively for 24V passive PoE ecosystems. It is not compatible with standard 48V PoE (802.3af, 802.3at, 802.3bt) devices. Before ordering, confirm that your target device's datasheet explicitly lists "24V PoE" or "passive 24V" as the power input specification. Deploying this adapter with an incompatible device risks equipment damage and system downtime.
Plan for adequate cabling length: standard Ethernet runs up to 100 meters support PoE without significant voltage drop over passive connections, but verify worst-case cable gauge and distance with your installer. If cable runs exceed 100 meters or use undersized gauge, consider a second power injection point.
Frequently Asked Questions
Q: Can I use the POE-24-24W-G-WH with standard 48V PoE devices like Axis or Hikvision cameras?
A: No. This adapter outputs 24V DC on a passive PoE line. Standard IP cameras and PoE devices expect 48V and active power negotiation (802.3af/at/bt). Connecting them will result in device malfunction or damage. Use only with devices explicitly rated for 24V passive PoE input.
Q: What input voltage does the POE-24-24W-G-WH require?
A: The adapter supports both AC and DC input. Refer to the product datasheet or the label on the unit itself for the specific input voltage range and connector specifications before connecting power.
Q: Is the POE-24-24W-G-WH suitable for outdoor use?
A: The unit itself is not weatherproof. Deploy it indoors in a network closet, rack, or protected cabinet. If you must locate it in a damp environment, place it inside a weatherproof enclosure and verify that the input/output connectors remain dry. For true outdoor power injection, consider a sealed PoE injector or mount the unit in a waterproof junction box.
Q: How much current can the POE-24-24W-G-WH deliver over a cable run?
A: With a 24W budget at 24V output, the adapter can supply up to approximately 1.0 amp at the output port. Verify that your cable gauge supports this current without excessive voltage drop. For runs longer than 100 meters or using Cat5 cable, confirm with your installer that voltage at the device remains above the minimum specified in the device's power input specification.
Q: Does the POE-24-24W-G-WH include a power cable or input connector?
A: Check the product documentation for package contents. You may need to source a compatible AC power adapter or DC connector separately to match your facility's power infrastructure.

The Ubiquiti POE-24-24W-G-WH is a straightforward passive PoE injector—no surprises, but read the fine print on voltage and power budget. This adapter assumes your field device is already rated for 24V input; if you're retrofitting legacy radio or antenna equipment, verify the original power spec first. The 24W ceiling is real: exceeding it will trigger shutdown or device damage.
Technical Highlights:
- 24V Passive PoE: No IEEE 802.3 negotiation—power is live immediately upon connection. That speeds deployment in remote and unattended locations, but it also means no handshake safeguards. Verify device input specs before connecting.
- 24W Power Budget: Sufficient for compact radios, sensors, and small antennas under 1.0 amp draw at 24V. Plan for voltage drop over cable runs longer than 75 meters or use Cat6 to minimize loss.
- Gigabit Passthrough: Single RJ-45 port handles both power and data, so no separate data line is required. Full 1 Gbps link negotiation ensures no network bottleneck between the injection point and the powered device.
Deployment Considerations:
- Voltage Compatibility Trap: This is 24V only. Connecting a 48V device (Axis, Hikvision, most commercial cameras) will destroy it. Check device datasheets explicitly—"PoE" alone does not mean 24V.
- Cable Run Planning: Passive PoE degrades over distance and undersized gauge. For runs beyond 100 meters, confirm with the cable installer that voltage drop won't fall below the device's minimum input specification (typically 20V at the load end).
- Cooling and Placement: No fan, so the unit is silent. Place it in a dry rack or closet where ambient temperature stays below 40°C to avoid thermal throttling of the power supply.
The POE-24-24W-G-WH is best suited to UISP ecosystems and Ubiquiti wireless backhaul links where 24V passive PoE is the standard. If you're building a mixed-vendor site with 48V PoE cameras, a standard PoE switch, or 802.3at injectors, this adapter adds complexity rather than solving it. For Ubiquiti-native deployments—tower-mounted radios, field sensors, distributed antenna units—it removes the cost and complexity of separate power supplies.
