AirLive POE-48TU PoE Splitter with Selectable DC Output
The AirLive POE-48TU separates incoming Power over Ethernet into Ethernet data and a dedicated DC power connection. It helps integrate compatible non-PoE equipment into a PoE-powered installation, reducing the need for a local AC outlet beside the device.
Designed for use with an IEEE 802.3af PoE source, the splitter accepts a nominal 48V PoE input and provides selectable 5V, 7.5V, 9V or 12V DC output. Applications include access points, customer-premises equipment and IP cameras whose electrical and connector requirements match the splitter.
Key Features
- IEEE 802.3af PoE input.
- Four selectable DC output voltages.
- Separate Ethernet data and DC power outputs.
- Supports 10/100 Mbps Ethernet connections.
- Allows suitable non-PoE devices to use a PoE network connection for power.
Power Selection
Select the voltage required by the connected equipment before applying power. Verify its operating current, startup demand, DC plug dimensions and polarity before installation. A matching voltage alone does not establish compatibility.
Connectivity
Connect the incoming PoE cable to the combined data-and-power input. Connect the separate Ethernet output and DC power lead to the destination device. The splitter is intended for Fast Ethernet applications.
Installation Considerations
For installations serving outdoor equipment, protect the splitter and its connections from weather. An outdoor enclosure rating has not been confirmed for this model.
Ideal Applications
- Adding suitable non-PoE equipment to an existing PoE installation.
- Supplying compatible network devices where local AC access is limited.
- Retrofitting access points, CPE devices and IP cameras after verifying their power requirements.
Compatible Products
The AirLive POE-48TU requires a suitable IEEE 802.3af PoE power source. The following injector provides standards-based power compatible with the splitter's PoE input:
- Intellinet 561518 Gigabit High-Power PoE+ Injector, 30W – Supports IEEE 802.3af powered devices and provides Mode A power on the Ethernet data pairs accepted by the POE-48TU.
The injector's Gigabit capability and 30W rating do not increase the splitter's Ethernet speed or DC output capacity.
Important: Downstream equipment must match the selected output voltage, available current, connector dimensions and polarity. The original POE-48TU documentation specifies a maximum of 2A at 5V but does not provide confirmed current ratings for every other voltage. No specific downstream device is recommended without those checks.
Important: Do not substitute a 24V passive PoE source. Use the injector's standards-based PoE operation.
