The one with -G in the model number at the end seems to have a gigabit port, the other one does not.

The injector transmits 48V/0.5A (24 watts). Your splitter converts the 48V into 12V, which also changes the ampere value to 2A.
The total power remains the same (12Vx2A = 24 watts).
Your end device only wants 1.2A, but that doesn't matter. It only takes as much as it needs as long as 12V is present.
Hoi Donnersturm,
yes, bought this exact set here a fortnight ago: Ubiquiti Passive PoE Injector (PoE Injector) and this Cloudkey: Ubiquiti UniFi Cloud Key Plus Gen 2
Works flawlessly.
Hello
Which Unifi AP is it exactly? Look in the specification of the corresponding product for the supply voltage.
For + Plus products (e.g. Ubiquiti UniFi AP AC-PRO-E) you should use an injector with 48V supply voltage (D-Link DPE101GI). The difference between the two adapters is that one has 100Mbps and the other 1000Mbps (1Gbps) Ethernet. You might also want to check the manufacturer's homepage.
I use Ubiquiti UniFi AP AC-PRO-E with D-Link DPE101GI, works perfectly.
No, you need a 48V PoE+ adapter. The passive ones from Ubiquiti are only suitable for a few devices.
This one goes: TP-LINK PoE Injector TL-POE150S (PoE Injector)
