Ubiquiti UACC-DUAL-POWER-INJECTOR Dual PoE Injector
Overview
The Ubiquiti UACC-DUAL-POWER-INJECTOR is a passive PoE injector designed to simultaneously power and network two endpoints—typically Wave-series access points—over a single infrastructure run. It consolidates power delivery and 2.5 Gigabit Ethernet connectivity into one compact unit, eliminating the need for separate power supplies at remote installations. The weatherproof enclosure and included mount kit make it suitable for pole or wall installations in outdoor and semi-exposed environments.
Key Features
- Dual 2.5 Gigabit PoE Delivery: Two independent RJ45 ports each provide 2.5G Ethernet with 48V passive PoE. This higher port speed reduces latency and overhead compared to standard 1G PoE injectors, an advantage when backhaul bandwidth or multi-device convergence matters.
- 100W Total Power Budget: Aggregate 100W across both ports supports two power-hungry endpoints simultaneously—critical when deploying dual Wave Pro units or similar high-draw devices. Calculate per-port allocation based on your endpoints' actual draw; this headroom prevents power bottlenecks.
- Passive PoE (48V): Uses non-standard 48V PoE, not 802.3af/at/bt. Ensure all connected devices (typically Wave models) are rated for 48V passive PoE; incompatible endpoints will not power on. This is not an 802.3 standard injector.
- Weatherproof Enclosure: Protects against rain and dust in pole-mount or wall-mount outdoor scenarios. Not submersion-rated; keep below eaves or under canopies if long-term water exposure is expected.
- Compact, Field-Installable Form Factor: Ships with pole and wall-mount kit, reducing on-site fabrication. Mount near the cable run to minimize PoE voltage drop over long distances—a common gotcha in extended outdoor deployments.
- Compatible with Ubiquiti Wave Series: The UACC-DUAL-POWER-INJECTOR (often searched as UACC DUAL POWER INJECTOR) explicitly supports Wave Pro, Wave Nano, and other Wave-family endpoints. Verify your specific endpoint's 48V PoE requirements before purchase.
Integration & Compatibility
This injector is part of the Ubiquiti product ecosystem and integrates directly with Wave access point deployments. It requires a standard Ethernet uplink from your core network or PoE switch to inject power on the downstream run. For larger multi-site Wave deployments, pair this with a managed PoE switch to distribute power across multiple injectors. Always validate cable gauge and run length against 48V PoE voltage-drop calculations—runs over 100m may require thicker gauge or voltage boosters.

Frequently Asked Questions
Q: Is the UACC-DUAL-POWER-INJECTOR compatible with standard 802.3af/at/bt PoE equipment?
A: No. This injector provides 48V passive PoE, not IEEE 802.3 standard PoE. Only connect devices rated for 48V passive PoE (such as Ubiquiti Wave models). Standard PoE cameras, switches, and other 802.3-compliant devices will not work with this injector.
Q: Can I power a single Wave endpoint with this injector if I only need one connection?
A: Yes. You can use one of the two 2.5G ports and leave the other unused. The UACC-DUAL-POWER-INJECTOR will still deliver full power and bandwidth to the connected device.
Q: What happens if the total power draw from both connected devices exceeds 100W?
A: The injector will not power both devices. Calculate your endpoints' actual power draw (check Wave datasheet specs) and ensure the combined total does not exceed 100W. If you need more power, use a second injector on a separate Ethernet run.
Q: Is the weatherproof enclosure submersion-rated?
A: The enclosure is weatherproof (resists rain and dust in outdoor pole/wall-mount applications) but not fully submersion-rated. Install in covered locations such as under eaves, inside weatherproof pedestals, or beneath canopies if long-term water exposure is a concern.
Q: How do I minimize voltage drop on long Ethernet runs with this injector?
A: At 48V, voltage drop is lower than 12V systems but still matters over extended distances. For runs over 100 meters, use Cat6A or thicker gauge cabling and consider mounting the injector closer to the endpoints. Measure voltage at the remote device to confirm 48V is being delivered; typical drop is 2–5V per 100m depending on wire gauge.

The UACC-DUAL-POWER-INJECTOR is a purpose-built accessory for Wave deployments—not a generic PoE injector. Its 100W budget and dual 2.5G ports are optimized for simultaneous Wave Pro or Nano endpoints, but the 48V passive PoE specification means it lives entirely outside the 802.3 ecosystem. That's a hard constraint: if you're mixing Wave and non-Wave endpoints, this injector won't help.
Technical Highlights:
- 2.5 Gigabit Port Throughput: Each port supports 2.5G Ethernet, not 1G. This reduces backhaul congestion on multi-AP deployments and keeps latency lower when Wave devices are pushing near-simultaneous traffic. Real-world gain depends on your upstream bandwidth; on a 1G or slower WAN, the 2.5G ports won't matter.
- 48V Passive PoE (100W Combined): Delivers 100W across both ports. This is enough for two high-draw Wave models. On a 48V rail, voltage drop becomes noticeable beyond 100m of standard CAT5e—you'll lose 3–5V depending on gauge. Plan accordingly on long outdoor runs.
- Weatherproof Enclosure with Mounts: Protects against rain and dust; includes pole and wall-mount hardware. The compact form factor is practical, but the enclosure is not sealed for prolonged submersion or direct spray.
Deployment Considerations:
- Wave-Only Ecosystem: Do not attempt to use this with non-Wave endpoints or standard PoE devices. 48V passive PoE is not backwards-compatible with 802.3af/at/bt. Verify endpoint datasheets before ordering.
- Power Budget Math: Check your two endpoints' actual power draw (Wave datasheet Typical Power consumption, not peak). If combined draw is over 100W, the injector will not reliably power both. This is a hard ceiling, not a soft limit.
- Voltage Drop on Extended Runs: Pole-mounted scenarios often mean 50–150m of cable. At 48V, a 2–3V drop is acceptable (still 45V+ at the device). Anything below 42V risks instability. For runs over 100m, upgrade to Cat6A or use a booster.
This injector is ideal for compact, dual-Wave outdoor deployments (mesh backhaul links, distributed antenna pole mounts, wall-mounted pairs). It's not a general-purpose PoE solution. If you're building a mixed infrastructure with other Ubiquiti or third-party devices, confirm 48V PoE compatibility first—or consider separate power supplies to avoid compatibility headaches.
