Our 48V to 12V 3A POE+ Active Gigabit POE Splitter – 5.5mm X 2.1mm Power Plug Tip – Outdoor POE Power LoRaWAN Helium Miner Router WiFi Hotspot Camera Power receives data and power over a single Cat7/Cat6A/Cat6/Cat5e Ethernet cable and splits the power and the data into two output cables (i.e, the 5.5mm x 2.1mm x barrel plug to provide 12 Volt 3 Amps of power to the device, and the RJ45 Ethernet cable to provide the data). This will allow a non-PoE, 12 volt DC powered device to be remotely installed and powered over the Ethernet cable (PoE). The Splitter requires a 40V to 56 Volt PoE (power adapter) Gigabit Injector that combines (and injects) the power and the data into a single ethernet cable and sends it to the Splitter. A 48V PoE power injector is typically used and may be installed within 100M of the Splitter. Our splitters recently were updated to work with active poe circuits.
