TP-Link TL-SF1005LP 5 Port 10/100 Mbps Desktop Switch compliance with the 802.3af PoE standard supports up to 15.4 W on each PoE port. The total 41 W PoE power budget for the 4x PoE ports opens up a wide range of applications, such as surveillance for offices, dormitories and small businesses. It is fully compatible with IP cameras, access points, IP phones, computers, printers and more. With extend mode, the PoE transmission distance reaches up to 250 m perfect for IP Camera deployment in large areas. Quality of sensitive applications like video monitoring in critical business areas is guaranteed by offering higher priority options for ports 1–2 when one-touch priority mode is on. The interior components of TL-SF1005LP are protected by high-quality metal casing to ensure a long product life. Having passed an array of stringent reliability tests, TL-SF1005LP delivers switching performance you can depend on. When total power consumption exceeds 41 W, the intelligent power management will cut the lower priority port power. This ensures the high priority port’s power supply and protects the device from power overload. It also automatically detects and provides the required power for your PoE devices while protecting your PoE and non-PoE equipment from being damaged.
