### 4. Functionality

The PD1301 functions as a PoE powered device (PD) module that extracts electrical power from a standard Ethernet cable supplied by a PoE power sourcing equipment (PSE), such as a PoE switch or injector. It converts the incoming 36–57VDC PoE voltage into a stable 12.5VDC output, capable of delivering up to 1.1A to the host device.

Operational Principle:
1. The PD1301 connects to an Ethernet interface that carries both data and power (PoE-enabled RJ45 connection).
2. The module’s auto-sensing algorithm detects the presence of an IEEE 802.3af-compliant PSE before drawing power.
3. Once validated, it negotiates power classification (Class 0) and begins power extraction.
4. The internal DC-DC converter regulates the voltage to 12.5VDC, supplying the host circuitry.
5. Built-in protection circuits safeguard against short circuits and overcurrent conditions.

Typical Use Cases:
- Integration into wireless LAN access points (WLAN APs) to eliminate external power adapters.
- Powering IP cameras, VoIP phones, IoT gateways, and embedded controllers.
- Suitable for industrial automation, security systems, and networked sensors.
- Ideal for OEMs developing PoE-capable devices without redesigning power infrastructure.

Compatibility:
- Compatible with all IEEE 802.3af-compliant PoE switches, injectors, and midspans.
- Works with Rayon’s PoE ecosystem, including FPI400/FPI401 (10/100Mbps injectors) and GPI4000/GPI4001 (Gigabit injectors).
- Can be paired with SP1301 or SP2401 PoE splitters for non-PoE devices.
