48 V 3 A 144 W power supply, 5.5/2.1 mm jack The Extralink 48 V power supply is equipped with a 5.5/2.1 mm jack connector and is used to power network devices using additional PoE injector solutions. In this way, you can power e.g. IP cameras or AP cameras. The product version with a power cable is terminated with a C14 computer connector. The LED indicates the correct operation of the device. If one of the short-circuit or overload protections is activated, the power supply cuts off the voltage from the device. After the failure stops, the voltage is restored automatically.
