RG-POE-AF15 Passive PoE Injector — 52 V DC, 15.6 W, 1-Port Gigabit

Introduction: What the RG-POE-AF15 Is and Why It Matters

The RG-POE-AF15 Passive PoE Injector from Ruijie/Reyee is a compact, single-port power injector designed to deliver 52 V DC at up to 0.3 A (≈15.6 W) while passing gigabit Ethernet data. It is aimed primarily at installers, small-business IT teams and enthusiasts who need a simple, reliable inline power source for compatible wireless access points, small IP cameras and other single-port PoE devices that accept 52 V passive PoE.

With a suggested retail price of approximately $14.99 and a manufacturing cost around $10.08, the RG-POE-AF15 is positioned as an affordable, no-frills solution for powering devices where standards-based PoE negotiation (802.3af/at) is not required. Its small footprint, wide AC input range and built-in surge protection make it a practical choice for desktop or closet installations where space and budget matter.

Detailed specifications and benefits

Understanding the technical details helps you decide whether the RG-POE-AF15 is suitable for your deployment. Below are the core specification groups and the practical benefits they deliver.

• Model: RG-POE-AF15
• Output voltage: 52 V DC
• Output current: 0.3 A
• Output power: ≈15.6 W
• Powering pairs: 2-pair (Pins 4,5 = + ; Pins 7,8 = −)
• Efficiency: ≈84.32%; Ripple: ≤ 200 mVp-p; Line/load regulation: ≤ 5%

Benefit: The 52 V passive output is a common requirement for certain vendor-specific wireless access points and cameras. At ~15.6 W the injector can power many small APs and cameras without the complexity or cost of higher-power active PoE solutions.

• AC input: 100–240 VAC, 50/60 Hz
• Input current (max): 0.5 A; Inrush current: < 80 A @ 230 VAC
• Network port: 1 × 1000Base-T (Gigabit) RJ‑45
• AC connector: IEC‑320 C8
• Switching frequency: 65 kHz

Benefit: Universal AC input and a standard IEC lead make the unit easy to install in many regions using a simple power cord. The gigabit data pass-through ensures full-speed network capability for devices that require high throughput.

• Surge / transient protection: differential & common mode protection
• Max surge discharge: 2000 A (8/20 µs) (per datasheet)

Benefit: Built-in surge and transient protection protects attached devices from common power anomalies, especially useful in installations where outdoor cabling or long runs can introduce spikes. This reduces downtime risk for small deployments.

• Operating temperature: −10 °C to +45 °C; Storage: −40 °C to +70 °C
• Operating humidity: 5–95% non-condensing
• Dimensions: ≈92 × 46.5 × 29.5 mm; Weight: ≈95 g

Benefit: The compact size and light weight make the injector easy to tuck into racks, closets or mounted near the powered device. Environmental ratings suit typical indoor deployments.

Installation, safety and important notes

• Passive PoE: This injector does not perform PoE negotiation (802.3af/at). Confirm the powered device accepts 52 V passive PoE before connecting.
• Disconnect mains before handling the AC lead or performing wiring changes.
• Use cabling rated for PoE and follow manufacturer installation instructions.
• Compliance markings (CE/UKCA) were not specified in the provided data; consult the manufacturer or supplier if regulatory certification is required for your region.

Use cases and scenarios where the RG-POE-AF15 excels

The RG-POE-AF15 excels in situations where a simple, low-cost inline power source is needed for devices that expect 52 V passive PoE. Typical scenarios include:

• Small office or branch Wi‑Fi deployments:When deploying vendor-specific access points that use passive 52 V power, the injector provides a tidy inline solution without requiring a PoE switch.
• IP camera installations:Compact indoor cameras that accept 52 V passive PoE can be powered using this injector, allowing remote placement without nearby mains outlets.
• Closet or desktop installations:Its small form factor makes it convenient for use in network closets, above ceiling tiles or on a desk next to the device being powered.
• Cost-sensitive rollouts and spare inventory:When budgets are tight or you need inexpensive spares for support teams, this injector is a low-cost option compared to managed PoE switches or higher-power midspans.

How it compares with similar products

Comparing the RG-POE-AF15 with other injectors highlights its strengths and limitations.

• Compatibility:Passive injectors provide fixed voltage and do not negotiate power. They are compatible only with devices that specifically accept that voltage. 802.3af/at injectors negotiate power and are universally compatible with standards-compliant devices.
• Cost:Passive injectors like the RG-POE-AF15 are typically less expensive than active 802.3af/at injectors or PoE switches.
• Safety and intelligence:Standards-based PoE provides power negotiation and classification which helps prevent damage to non-PoE devices; passive injectors lack those protections.

• Surge protection:The RG-POE-AF15 includes differential and common-mode surge protection with a high discharge rating. Some lower-cost passive injectors omit robust surge protection, making the RG-POE-AF15 a safer choice in environments prone to electrical transients.
• Gigabit passthrough:Full gigabit pass-through is standard on higher-quality injectors. Cheaper models sometimes only support 10/100 Mbps or use power wiring that degrades performance.
• Physical design:Its small size and IEC power input make it convenient compared to bulky external power bricks or units with fixed regional cords.

Limitations to be aware of

• Because it is passive, it can damage non-compatible devices if the voltage/pinout expectations differ.
• Output power is limited to ~15.6 W, so it cannot support higher-power access points, PTZ cameras or devices requiring 802.3at class power.
• Warranty and region-specific certifications were not provided in the supplied data; purchasers who require certified compliance should verify with the vendor.

Customer feedback and representative comments

Official, verified customer reviews were not included in the provided data. Below are representative, anonymized comments that reflect common installer and small-business feedback for products of this class (illustrative only):

• "Great little injector for our branch APs — compact and works reliably. The surge protection gave us extra peace of mind near exterior runs."
• "Saved us money when the site used vendor-specific passive PoE APs. Easy to deploy and gigabit speed works fine."
• "Make sure your device accepts 52 V passive PoE — we learned that the hard way with one non-compatible camera."

If you need verified customer reviews, check reseller pages or industry forums where buyers post real-world experiences for this specific model.

Conclusion: Why choose the RG-POE-AF15?

The RG-POE-AF15 Passive PoE Injector is a focused, budget-friendly solution for powering devices that require 52 V passive PoE and gigabit data throughput. Its compact design, wide AC input range and built-in surge protection make it an attractive choice for small offices, branch sites, and installers who need a simple inline power source without the complexity or cost of standards-based PoE switches.

It is not a one-size-fits-all product: its passive nature and 15.6 W power limit mean you must confirm device compatibility and power requirements before purchase. For environments that need higher power, active PoE negotiation, or guaranteed certifications documented for regulatory compliance, a standards-based PoE injector or managed PoE switch will be the better option.

For those who have devices that accept 52 V passive PoE and seek a low-cost, space-saving injector with surge protection and gigabit support, the RG-POE-AF15 represents a practical, value-driven choice.
