48V to 12V Gigabit PoE Splitter

Q1: What does the PoE splitter do?

The main function of a poe power splitter is to separate the power and data signals transmitted over a network cable, allowing devices that do not support PoE to function normally through a PoE network. It is typically used in conjunction with a PoE switch or PoE power supply to split the power and data in a single PoE cable into independent DC power outputs and network data interfaces, thus providing stable power to ordinary network devices while maintaining normal data communication.

Q2: How does a PoE power splitter separate power and data?

A outdoor poe splitter integrates PoE detection and power conversion circuitry. When a PoE cable is connected to the poe camera splitter, the device first identifies the PoE power signal and then separates the power and data signals through its internal circuitry. The separated data is output to network devices via an RJ45 interface, while the power is converted to the voltage required by the device (e.g., 5V, 9V, or 12V) via a DC-DC converter and output through the DC interface to power the terminal devices.

Q3: Do PoE splitters need an external power supply?

Generally, a ethernet power splitter does not require an external power supply. It draws power directly from the network cable supplied by the PoE switch or PoE injector and converts it to a DC voltage suitable for the device. Therefore, as long as PoE power is provided on the network side, the poe ethernet splitter can provide both power and data output simultaneously, simplifying cabling and reducing the need for additional power adapters.
