This IEEE 802.3af PoE splitter separates power and data from a single PoE Ethernet cable, providing selectable regulated DC output (5V, 9V, or 12V) at up to 1A alongside a standard Ethernet data connection. A DIP switch on the unit lets you select your desired output voltage.
The splitter accepts 44–57V PoE input, supports 10/100 Mbps data transmission, and includes four interchangeable DC plug adapters with positive-tip output to fit a wide range of devices.

Jargon buster
Plain-language definitions for the technical terms used above.
- DC
- DC means direct current, where electricity flows in one constant direction, as supplied by batteries, USB ports and many plug-pack power supplies. When a product specifies DC, it runs from a DC supply rather than mains AC, so you need to provide the correct voltage and polarity.
- DIP switch
- A DIP switch is a small set of physical on/off switches used to configure hardware settings without software. It matters because changing features such as auto power-on or charging limits may require moving these tiny switches correctly.
- PoE
- Power over Ethernet lets one Ethernet cable carry both network data and electrical power. This is useful when installing a device where running a separate power adaptor would be difficult.
