E-link Launches LNK-AIPSE301M60 AI Smart PoE++ Injector with LED Screen Display: 60W IEEE 802.3bt Output
2026-11-03
E-link Introduces the LNK-AIPSE301M60 AI Smart PoE++ Injector with LED Screen Display E-link is proud to announce the release of the LNK-AIPSE301M60 AI Smart PoE++ Injector, a compact gigabit PoE injector that combines a 60W IEEE 802.3bt power budget with a brand-new visual intelligent design. Built for system integrators, installers and OEM partners, this single-port injector solves one of the most common site problems in IP surveillance and wireless deployment: how to power a high-draw PoE++ device where no AC outlet exists. Power High-Demand Devices Over a Single Cable The LNK-AIPSE301M60 connects a non-PoE LAN switch to IEEE 802.3af/at/bt PoE++ powered devices such as PTZ speed dome cameras, AIO (All-in-One) touch PCs and remote digital signage displays, delivering both data and power over one Ethernet cable with transmission distances up to 100 meters. Because the injector carries its own PSE controller, no PoE-capable switch is required — legacy networks gain full 802.3bt capability without any switch replacement. Backward compatible with IEEE 802.3af (15.4W) and IEEE 802.3at (30W) standards as well as the newer 802.3bt 60W class, the unit supports 10/100/1000Base-T on both the data-in and PoE-out ports, with full-duplex flow control (IEEE 802.3x) and Energy Efficient Ethernet (IEEE 802.3az). Power pin assignment covers both End-span and Mid-span (1/2+, 3/6-; 4/5+, 7/8-), and the injector is compatible with Mode A and Mode B classification. Headline Feature: LED Screen Display with Auto-Scrolling Live Data The defining feature of the LNK-AIPSE301M60 is its LED Screen Display — a built-in AI Smart visual panel that no conventional PoE injector in this class offers. Instead of plugging in a handheld tester, engineers can read live device status directly from the front panel. The screen auto-scrolls through a real-time data dashboard showing: PSE supply voltage — confirm the injector is delivering the expected PoE voltage PoE power consumption — verify the actual wattage drawn by the powered device IEEE 802.3 class — identify af / at / bt classification at a glance Mode A & Mode B classification — validate the power negotiation mode Internal temperature — monitor thermal condition in enclosed cabinets or outdoor enclosures For installation teams this turns commissioning and troubleshooting into a visual, first-time-right process. Field engineers can confirm power delivery, load and device class in seconds, cutting truck rolls and repeat site visits caused by "no PoE" callbacks. Built for Demanding Environments The injector accepts a wide AC input range of 85–265 VAC, 50–60 Hz, so the same unit can be stocked for markets worldwide without voltage-specific SKUs. No-load power consumption stays below 0.5W, helping projects meet energy budgets, and the design complies with Limited Power Source (LPS) requirements. Protection is comprehensive: over-voltage, over-load, over-temperature and short-circuit protection, plus 1kV lightning surge protection on all ports, 4kV/8kV ESD and 500W power surge capability. The fanless ABS+PC casing measures just 146 × 60 × 37 mm and weighs 400 g, mounting on a wall with a wide operating range of -10 °C to +60 °C and MTBF above 200,000 hours. Key Technical Specifications Parameter Specification Model LNK-AIPSE301M60 Access mode 1-port 10/100/1000Base-T RJ45 in to 1-port 10/100/1000Base-T RJ45 PSE out PoE standard IEEE 802.3af / at / bt PoE++ PSE (15.4W / 30W / 60W) PoE power output 60W max., budget up to 60W Power pin assignment End-span + Mid-span: 1/2(+) 3/6(-); 4/5(+) 7/8(-) Processing type Store-and-forward Forward / filter rate 14,880 pps (10M) / 148,800 pps (100M) / 1,488,000 pps (1000M) Input power 85–265 VAC, 50–60 Hz Power consumption < 0.5 W (no load) Cable / distance Cat5e or above, ≤100 m at 1000M, ≤250 m at 10M Dimensions / weight 146 × 60 × 37 mm / 400 g Operating temperature -10 °C to +60 °C Surge protection RJ45 1KV, Power 500W, ESD 4KV/8KV Approvals ISO9001, CE, FCC Part 15 Class A, RoHS, EN55022 Class A Typical Applications PTZ speed dome cameras — 60W headroom for pan-tilt-zoom motors, heaters and defoggers AIO touch PCs and interactive displays — power meeting-room and kiosk terminals without extra outlets Remote digital signage — power screens mounted on walls, ceilings or other hard-to-reach locations Wi-Fi 6/6E and 5G access points — support higher-power radios and backhaul units Any network device requiring higher PoE input power Fewer Cables, Faster Installs, Lower Cost By removing the requirement for a nearby AC socket, separate power cabling and licensed electrician work at every camera or display location, the LNK-AIPSE301M60 reduces material cost, cabling labor and installation time on PoE projects. Deployment constraints caused by power-socket locations disappear, and power outlets on walls, ceilings or hard-to-reach places are no longer mandatory.
