Introduction to the Ruijie (Reyee) RP028-2400500 and its key features
Ruijie (Reyee) RP028-2400500is a compact, single‑port passive PoE injector purpose‑built to power Reyee/Ruijie wireless bridge devices over Ethernet cabling. It converts universal AC mains (100–240 V AC) into 24 V DC and injects that power onto the data pair of a 10/100 Mbps Ethernet link, supplying up to 0.5 A (12 W) to compatible devices. The unit is straightforward, cost‑effective and commonly used by installers and network technicians in deployments where a local DC power source is unavailable.
Key features at a glance:
- Passive PoE injector delivering 24 V DC at 0.5 A (12 W)
- Single 10/100 Mbps Ethernet data+power port
- Universal AC input: 100–240 V
- Typical protections: overcurrent, overvoltage, and short‑circuit
- Compact and wallet‑friendly — suggested resale price around $9.99 (wholesale cost typically low)
Detailed description of specifications and benefits
The RP028‑2400500 is intentionally simple in design, and its specification sheet reflects that single‑purpose focus. Each key spec is paired with practical benefits for installers and end users.
- Output voltage:24 V DC — a common voltage for many Reyee/Ruijie bridge devices. Using the correct voltage avoids damage and ensures reliable operation of the powered device.
- Output current:0.5 A (500 mA) — sufficient for many point‑to‑point radios and small wireless bridges that require modest power budgets.
- Output power:12 W — adequate for devices specified to run from passive 24 V PoE, but lower than what active IEEE PoE standards can deliver.
- Input voltage:100–240 V AC — makes the injector usable in most regions without a separate power adapter for different mains voltages.
Benefit: The wide AC input and compact DC output make this injector easy to deploy in diverse environments with minimal extra hardware.
- Ethernet:1 × 10/100 Mbps data port — compatible with most legacy and current Reyee bridge models that use Fast Ethernet.
- PoE type:Passive PoE (single‑port) — the injector applies DC voltage directly to the cable pairs used by the target devices rather than negotiating power via IEEE 802.3af/at protocols.
Benefit: Passive PoE keeps the injector simple and cheap. It is optimized for devices that explicitly expect 24 V passive power, giving an uncomplicated plug‑and‑play experience when used with compatible hardware.
- Protections:Typical overcurrent, overvoltage and short‑circuit protection — these help reduce the risk of damage from faults on the line.
- Packaging note:The mains lead may not always be included — installers should confirm pack contents before deployment to ensure they have the right lead for their region.
- Lifecycle:End of Sale announced (last sell date 25 Jun 2025) with End of Support on 25 Jun 2026 — check stock and support status before bulk procurement.
Benefit: While the unit includes basic protections, the End‑of‑Sale status signals buyers to consider stock availability and future replacement options when planning larger installations.
Use cases and scenarios where the RP028‑2400500 excels
The RP028‑2400500 is tailored to a few clear scenarios where a simple, reliable 24 V passive power source is preferred over more complex (and expensive) alternatives.
- Primary scenario: powering models such as RG‑EST310 V2 and RG‑AirMetro460F — these devices are frequently designed to accept passive 24 V PoE, making the injector an ideal match.
- Advantage: ensures the radio can be mounted where AC mains are not available, using a single Ethernet cable for both data and power.
- Installers mounting a single bridge or radio on a roof, pole or balcony can run one Ethernet cable from the injector inside the building to the outdoor device.
- Advantage: compact size and low cost make it easy to stock for ad hoc jobs and repairs.
- Events, short‑term links, or temporary networks where you need quick, reliable power without investing in managed PoE switches.
- Advantage: low cost and plug‑and‑play behavior reduce setup time.
Because it is a passive injector, ensure the connected device is explicitly specified to accept 24 V passive PoE. Passive injectors do not perform handshakes with powered devices, and connecting them to equipment expecting IEEE PoE can damage hardware. When in doubt, consult the device manual or contact the vendor.
Comparisons with similar products in the market
To understand where the RP028‑2400500 sits in the market, it helps to compare it with two alternative approaches: active IEEE PoE injectors/switches and other passive single‑port injectors.
- Power negotiation:Active PoE negotiates power (PD/PD class) and supplies up to 15 W (802.3af) or 30–60 W (802.3at/802.3bt). The RP028 is passive and fixed at 24 V/0.5 A (12 W).
- Compatibility:Active PoE is broadly compatible with IEEE‑compliant devices. The RP028 is intended for devices that specifically accept passive 24 V.
- Cost:Active PoE injectors and managed PoE switches are typically more expensive. The RP028 is much cheaper and simpler — a budget‑friendly option for supported devices.
- Use case fit:For Reyee bridges designed for 24 V passive input, the RP028 provides a direct and inexpensive solution. For heterogeneous deployments with mixed PoE devices, active PoE is safer and more flexible.
- Specifications:Many passive injectors are available with different voltages (12 V, 24 V) and currents. The RP028’s clear focus on 24 V/0.5 A matches a common set of Reyee devices.
- Build & protections:Competitors may offer similar protections; differences usually come down to build quality, connector quality and extra features (LEDs, fuse accessibility).
- Price & availability:The RP028 is competitively priced. Its End‑of‑Sale status, however, means availability may become limited — other brands may provide longer‑term availability or different warranty terms.
Customer feedback and typical reviews
No official public testimonials were provided with the item details, but common themes from installers and small business users who adopt simple passive PoE injectors for compatible devices include:
- "Value for money" — many users appreciate the low price and simple operation for compatible hardware.
- "Reliable for single‑device links" — when used with the correct Reyee device, installers report stable operation and straightforward wiring.
- "Double‑check compatibility" — a recurring caution from experienced technicians is to verify the device accepts 24 V passive PoE to avoid damaging non‑compatible equipment.
- "Packaging and leads" — some buyers note the mains lead is sometimes not included, so it’s important to confirm what you receive to avoid last‑minute trips for regional power leads.
These representative points reflect the product class: simple, effective and economical when used correctly, but requiring awareness of compatibility and supply details.
Conclusion — why the RP028‑2400500 is a great choice
The Ruijie (Reyee) RP028‑2400500 is a purpose‑built, no‑frills solution for powering Reyee and Ruijie passive 24 V wireless bridges. If your deployment consists of devices explicitly specified for 24 V passive PoE, this injector offers a low‑cost, compact and reliable way to deliver power and data over a single cable. It excels in single‑device rooftop installs, temporary links and any situation where a simple, inexpensive injector is appropriate.
However, buyers should be mindful of two important caveats: passive PoE requires explicit device compatibility (there is no IEEE power negotiation) and this specific model has a published End‑of‑Sale date, which may affect long‑term procurement and support. Confirm pack contents for the mains lead and consider stock levels before scaling a deployment.
For budget‑conscious installers and technicians working specifically with Reyee‑branded bridges like the RG‑EST310 V2 or RG‑AirMetro460F, the RP028‑2400500 remains a sensible, practical choice — simple to deploy, easy to stock, and purpose‑matched to the job.
