Frequently asked questions
Which one handles multiple devices better?
The PSR5.4 delivers 5.4A at 12VDC, making it suitable for several moderate-draw devices wired in parallel. The PS-POE-AF-TC delivers 15.4W total at 48V over Ethernet, best for single or a few lightweight PoE-compliant devices on a network backbone.
Can I use these for portable or mobile setups?
Neither is ideal for mobile work. The PSR5.4 requires wall mounting and wall power; the PS-POE-AF-TC is desktop-mounted and needs AC mains. Both are built for fixed installations.
What is the main wiring difference?
The PSR5.4 connects via a 3.5mm Phoenix connector for direct DC delivery; you must run separate power cables. The PS-POE-AF-TC injects 48V onto Ethernet cable pins, combining data and power in one standard network cable run.
Which one requires more technical skill to install?
The PS-POE-AF-TC is beginner-friendly—plug AC power, connect Ethernet in and out, and the diagnostic LED confirms operation. The PSR5.4 requires professional-level rack or cavity installation and proper DC wiring routing.
