Product Description The LNK-AIPSE301M90 is a world-first AI smart visual Gigabit PoE Injector that eliminates the "blind operation" pain point of traditional PoE injectors. Equipped with an LED display, it delivers real-time readings of PoE output voltage, current power consumption, PD device class, and internal temperature at the touch of a button. Field engineers can quickly diagnose link status without carrying a multimeter or additional test tools, dramatically improving deployment efficiency and troubleshooting speed. Compliant with IEEE 802.3af/at/bt standards, this injector provides up to 90W of PoE output per port and supports both End-span and Mid-span power pin assignments (Mode A & B). It allows you to connect to any non-PoE LAN switch, delivering both data and power over a single Ethernet cable to PTZ speed domes, wireless APs, digital signage, and more, with transmission distances up to 100 meters. Built with a high-quality power supply, it supports 85–265V AC wide voltage input, along with 1KV surge protection, over-voltage, over-load, and short-circuit protections to ensure safe and stable operation. Housed in an IP40-rated aluminum casing, the injector operates reliably in harsh environments from -14 F to 136 F. It requires zero configuration—simply plug and play. With no-load power consumption below 0.5W and compliance with LPS (Limited Power Source) standards, it is both energy-efficient and environmentally friendly. Choose it for a smarter, more reliable PoE networking experience.
