E-link PoE Switche

The LNK‑AINJ301M90 is a compact AI smart‑managed industrial PoE++ injector independently developed by E‑link. Compliant with IEEE 802.3bt, it delivers up to 90W PoE power output with an onboard voltage booster. This innovative unit merges advantages of both managed and unmanaged PoE hardware.

Real‑time operational data can be accessed via local LED digital display, Android mobile APP, or PC‑based Web UI. Even non‑technical field technicians can complete on‑site configuration & troubleshooting quickly.

Featuring an IP40‑rated aluminum housing, DIN‑rail mounting, dual redundant power inputs, and an ultra‑wide operating temperature range of‑40°C ~ +75°C, it ensures rock‑solid 24×7 performance under harsh industrial conditions.

Key Product Highlights

1. **Full‑status Visualization**
Read real‑time system voltage, current, internal temperature, and Ethernet link speed directly from the front‑panel LED screen. Intuitive graphical UI on APP / Web replaces complex traditional management pages for easy status review.

2. **Wide DC Input & Built‑in Voltage Booster**
Wide‑range DC input from 9‑54V. PoE output power dynamically adapts according to input voltage:

- 12V input → Max 60W PoE output
- 24V / 48V input → Max 90W PoE output

3. **Full PoE Protocol Compatibility**
Supports IEEE 802.3af / at / bt PoE++ standards with both Mode A & Mode B. Custom‑tuned hardware versions are available for Starlink Gen2 / Gen3 terminals.
4. **AI‑Powered O&M Features**
Scheduled system reboot, scheduled PoE port restart; auto‑recovery redundancy mode. When the target port goes link‑down, traffic will be forwarded to the backup link automatically.
5. **Industrial‑Grade Hardware Protection**
6KV lightning surge protection on all ports; fan‑less aluminum heat dissipation; dual redundant power supply for non‑stop operation.
