Cost-Effective Network Expansion: Add Power over Ethernet capability to any non-PoE or PoE only switch without replacing existing infrastructure. Each port delivers up to 30W (802.3at/PoE+) for powering WiFi access points, security cameras, VoIP phones and more. Intelligent Device Protection: Unlike passive injectors, this active 4 port PoE injector negotiates with connected devices using Mode A power delivery (pins 1,2- / 3,6+), only supplying power when a compatible device is detected - protecting non-PoE equipment from accidental damage. Power with Protection: Includes a 48 volt 60 watt supply. This PoE injector allows you to intelligently distribute power across multiple devices with self-resetting 650mA fuses per port for continuous operation assurance and built-in overload protection.
