### 4. Functionality
The SP2401 PoE Splitter functions as an intermediary device that separates power and data transmitted over a single Ethernet cable. When connected to a PoE-enabled switch, injector, or hub, it extracts the DC power supplied through the Ethernet cable and converts it into a regulated 12.5VDC output suitable for powering non-PoE devices.
Operational Process:
1. Input Connection: The SP2401 receives combined power and data signals through its RJ45 PoE input port.
2. Power Extraction: The internal PoE interface identifies the presence of an IEEE 802.3at-compliant power source using an auto-sensing algorithm.
3. Voltage Conversion: The device converts the 36–57VDC input to a stable 12.5VDC output.
4. Data Pass-Through: Ethernet data is passed through to the output RJ45 port without interference.
5. Output Delivery: The regulated DC output is provided via a dedicated power connector to the connected non-PoE device.
Use Cases and Applications:
- Powering non-PoE IP cameras, VoIP phones, and wireless access points.
- Supplying power to embedded systems, industrial controllers, and IoT gateways.
- Enabling PoE functionality in legacy network devices.
- Integration into custom hardware designs requiring compact PoE power modules.
- Suitable for office networks, industrial automation, and remote monitoring systems.
