AMX PS3.0 Power Supply - 12VDC 3.0A 1.3mm Barrel Connector vs AMX PS-POE-AF-TC PoE Injector - 802.3af
The AMX PS3.0 is a direct DC power supply for fixed AV control systems and studio equipment, while the AMX PS-POE-AF-TC is a network PoE injector that combines power and data over ethernet for networked devices. Choose the PS3.0 if you need basic 12V barrel-connector power; choose the PoE injector if your devices require both network connectivity and power delivery over a single ethernet cable.

- ✓ Universal 100–240V AC input works globally; load diagnostic LED and overload protection included
Frequently asked questions
Which one powers networked devices?
Only the PS-POE-AF-TC delivers power via ethernet using the IEEE 802.3af standard. The PS3.0 provides DC power through a barrel connector only, with no network capability.
What's the voltage and power difference?
The PS3.0 outputs 12 VDC at 3.0A (36W max). The PS-POE-AF-TC outputs 48V DC at up to 15.4W via ethernet. Choose based on your device's power input requirements and connector type.
Can either power portable equipment?
Both are optimized for fixed installations. Neither is recommended for portable or mobile applications; the PS3.0 requires a barrel connector and the PoE injector requires an ethernet port and standard AC wall outlet.
Which installation is simpler?
The PS3.0 requires only a barrel-plug connection to each device. The PoE injector requires an ethernet run from the injector to compliant PoE devices, but eliminates the need for separate power cables to those devices.
