Can be used with v2 Loudspeaker & Paging Amps for extra power. The new PoE power injector 802.3at is used with CyberData's new V2 Paging Amplifier (Part # 011061) and V2 Loudspeaker Amplifiers (AC - Part #011095 and Wireless - Part #011096) to provide up to 25 watts of driving power. 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.
