The Acconet POE-55V-90W (PSE90WI) is a high-power Gigabit PoE injector that provides 55V DC at 1.63A, delivering up to 90 watts of power over Ethernet. Compliant with IEEE 802.3af/at/bt standards, this PoE++ injector is designed to power high-demand devices such as PTZ cameras and industrial wireless access points. It features two Gigabit RJ45 ports—one for PoE output and one for data input—ensuring full wire-speed switching and support for jumbo frames. The injector includes port-level lightning surge protection for enhanced reliability. Constructed with a durable metal housing, it offers a plug-and-play design for straightforward installation. Key specifications include a 55V passive PoE output at 1.63A (maximum 90W), IEEE 802.3af/at/bt compliance, auto MDI/MDIX, full-duplex flow control (IEEE 802.3x), half-duplex back pressure, store-and-forward switching, and jumbo frame support on all ports. The power pinout is 12+/45+, 36-/78. This injector is suitable for both commercial and industrial applications.
