Dahua PFA111 PoE-injector-adapter – Gigabit, IEEE 802.3af, 48V, 15.4W

The Dahua PFA111 is a Gigabit Power over Ethernet (PoE) injector that combines data and power delivery over a single RJ45 cable. With a power output of 15.4W per port and compliance with IEEE 802.3af, it is an efficient solution for powering IP cameras, wireless access points, and edge network devices where power outlets are not readily available.

Advantages

This PoE injector simplifies network infrastructure by eliminating the need for separate power lines. It supports 10/100/1000 Mbps Ethernet speeds, ensuring compatibility with standard network equipment. The PFA111 features robust surge protection (4KV) and operates in a wide temperature range from -10°C to 55°C, making it suitable for both indoor and semi-outdoor installations.
