From: $25.43

Description

The 48V to 12V 3A POE+ Gigabit 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.

The PoE Splitters supports Mode A (Pins 1,2 + 3,6-) and B (7,8 + 4,5-) for both IEEE 802.3af /802.3at standard protocol for supplying DC power.

802.3af (PoE) can deliver up to 15.4 watts per port over network cables with 12.95W assured to be available at the powered device.

802.3at (PoE+) can deliver up to 30 watts over network cables with 25.5 watts available to the receiving devices.  For this reason, PoE Plus is also known as High PoE.

The unit’s data rate of Gigabit 10/100/1000 (GbE) transfer supports an ultra-fast maximum data rate of 1 Gigabit per second (Gbps – 1000 Mbps) and does not affect the speed performance of the local area network and devices.

The Splitter is equipped with a 5.5mm x 2.1mm barrel power plug which is compatible with most cellular router power connectors, as well as with numerous types of adapters.

    Thanks for clarifying , that helps a lot!

    802.3at spec is max-ed out at 25.5 watts – 12v at 3A = 36 watts. Is this a mistake ? What is the actual max power output at 12V?

      Hi John,

      Apologies for any confusion from the description.

      This is a passive throughput device so technically it has no PSE ratings as it doesn’t create the power like a POE power source would, it merely passes a stepped down (48VDC to 12VDC) voltage to a 2.1mmx5.5mmx10mm barrel plug. It is neither a PD or PSE, but a “means for separating power”. The 3A 12VDC rating is in reference to the maximum output rated on the 2.1mm barrel plug, for this specific device, when a 48V PoE power source is applied to it’s “input” ethernet port.
      You are referring to the 802.3 spec power parameters. Since this device is not a PSE or a “Powered Device”, it technically does not fall under these categories, though we definitely need to ensure which spec it would be capable for use for, as a “device that separate the power and data signals”. We mention the 802.3 POE and POE+ (af & at respectively) standards as reference to the power sources that can be used with our PoE splitter. It can handle POE++ input ( up to 100W max), but will only reliably output a maximum of 36W of power, at 12VDC, on the power plug output.

      I hope this helps, and let us know if you need any other information or clarifications and we will do our best.
