POE Splitter 12V 3A

　　A POE splitter 12V 3A is a specialized device designed to separate power and data signals from a single Power over Ethernet (PoE) cable, converting the incoming PoE power into a 12V DC output with a maximum current of 3A. This allows non-PoE devices to receive both power and data through a single Ethernet cable, eliminating the need for separate power adapters and simplifying installation in networked environments.

　　The primary function of a POE splitter 12V 3A is to extract the DC power from the PoE signal, which typically conforms to IEEE standards such as 802.3af (15.4W) or 802.3at (30W). The splitter takes the combined power and data signal from the Ethernet cable, separates the two, and delivers the data to the device via an Ethernet port while providing 12V 3A power through a DC jack. This makes it ideal for powering devices like IP cameras, wireless access points, small network switches, and VoIP phones that require 12V power but lack built-in PoE capability.

　　In terms of technical specifications, a high-quality POE splitter 12V 3A features overvoltage protection, short-circuit protection, and overcurrent protection to safeguard connected devices from electrical damage. It operates within a wide input voltage range, typically accepting 44-57V DC from the PoE injector or switch, and efficiently converts it to a stable 12V output. The 3A current rating ensures it can handle devices with power consumption up to 36W (12V × 3A), making it suitable for mid-power devices.

　　Installation is straightforward: the splitter connects to the PoE-enabled switch or injector via an Ethernet cable, and the output ports (one for data, one for 12V power) link to the target device. This is particularly beneficial in locations where power outlets are scarce, such as ceilings, walls, or outdoor enclosures, as it reduces cable clutter and simplifies maintenance.

　　Moreover, the POE splitter 12V 3A is designed to work with Cat5e or higher Ethernet cables, ensuring reliable data transmission at speeds up to 1000Mbps without interference from the power signal. It often has a compact, durable housing, making it suitable for both indoor and outdoor use, with some models featuring weatherproofing for outdoor installations.

　　Overall, the POE splitter 12V 3A is a versatile solution for integrating non-PoE devices into PoE networks, offering cost savings, easy installation, and reliable power delivery for a wide range of networked equipment.
