The principle of POE power supply and its power supply process:

1.Initially, the PSE device outputs a very small voltage at the port until it detects that the cable terminal is connected to a receiving terminal that supports the IEEE 802.3af standard.

2. PD device classification

When the receiving device PD is detected, the PSE device may classify the PD device and evaluate the power loss required by the PD device.

3. Start power supply

During a configurable time (typically less than 15μs), the PSE device begins to supply power from the low voltage to the PD device until a 48V DC power supply is provided.

4. Power supply

For the PD device to provide a stable and reliable 48V DC power to meet the PD device does not exceed 15.4W power consumption.

5. Power off

If the PD is disconnected from the network, the PSE will quickly power the PD device (typically within 300 to 400 ms) and repeat the detection process to detect if the terminal of the cable is connected to the PD.
