The Power Injector 802.3at eliminates the need for a PoE enabled hub. In a typical installation, the Power Injector is connected between a non-PoE hub and a CyberData paging device, providing inline power capability to an Ethernet Cat 5 cable. The new PoE power injector 802.3at is used with CyberData’s new V2 Paging Amplifier and V2 Loudspeaker Amplifiers to provide up to 25 watts of driving power.
