Question 1

Does this come with a AC>DC wall wart/block adapter?  Or is this just the injector and you supply the 48VDC power supply?

Accepted Answer

The confusion is about which of the models is selected and what their purposes are. The INJECTOR comes with a wall wart. The SPLITTER does not. Here's why; The INJECTOR supplies DC voltage TO the CAT5 cable which then connects to a POE capable device. The SPLITTER splits power FROM a powered CAT5 cable into two outputs - one is to the Ethernet data cable. The other is for a DC power cable to power a non-POE device. The KIT comes with BOTH devices.  The TL-POE-150S INJECTOR user guide, page 3 states: "Connect to the provided power adapter which can supply steady power of 48V DC." The injector connects to a POE capable device using only the powered CAT5 cable.The SPLITTER, however, does not have a wall wart, but instead uses the power from an injector connected to it by a CAT5 cable. The Splitter splits the power from the cable to a jack that has a selectable voltage output for a Non-POE capable device needing power and Ethernet connection.See http://static.tp-link.com/resources/document/TL-POE150S_V3_User_Guide.pdf for the user guide for the ADAPTER.Note - you can connect non-POE devices to a POE network, so you do not need two ethernet networks. However, POE devices can't be powered on a non-POE ethernet network, and some POE devices can't power other POE devices. POE devices can receive and send data over a non-POE network, but they must be powered from another source like a wall wart or other power supply.

Question 2

What is the output amps?

Accepted Answer

Just checked mine, and the label on the back says that the output is 48 volts DC at 0.35 amps.

Question 3

I will be using this for IP camera. What is the difference between injector and splitter? I see there is a cost differance but they look the same.

Accepted Answer

Short answer; a network injector combines ethernet and power and sends it over your ethernet cable.  A splitter does the reverse. It separates the power from the ethernet cable.

Used together; they are a handy way to remotely power a device that cannot be powered by simply using POE (power over ethernet). I used them to power an unmanaged switch in my attic, which I cannot power with a wall wart.  Then I can run cable drops to network demanding equipment instead of connecting wirelessly. (like a gaming console and 4K Roku's)  My mesh WIFI only  provides around 60-100Mbps and I get over 900Mbps using an ethernet cable.

Question 4

Has anyone hacked their own splitter to the other end of this thing? What pair is used for (+) and what pair is used for (-) V? Ya ya, be careful...

Accepted Answer

According to the 802.3af standard that this device adheres to, Mode B will allow a "hacked on" passive splitter on the other end. The flip side is that while the specification requires support for both Mode A and Mode B the power injector automatically decides which mode to use and your "splitter" or end device has no choice in the matter. "In mode B, pins 4-5 (pair #1 in both T568A and T568B) form one side of the DC supply and pins 7-8 (pair #4 in both T568A and T568B) provide the return; these are the "spare" pairs in 10BASE-T and 100BASE-TX. Mode B, therefore, requires a 4-pair cable." I purchased the TP-Link POE splitter, it is cheap, easy, works great. Mine had a choice of 3 common voltages (5v, 9v, 12v I believe) but other splitters have only 2 output voltage choices.
