The ZZ-PART PoE Splitter enables the conversion of non-PoE devices to Power over Ethernet. It is compatible with DC voltage 44-57 standard PoE switches and features overvoltage protection. This splitter divides the PoE signal into 12V DC power and 10/100Mbps Ethernet data, making it ideal for use with the SC-P620 Horn Speaker, allowing it to be powered from a PoE network switch instead of an external AC power supply.
