The Rack Chassis with Internal Power Supply, 9 VDC, 12 VDC, and 48 VDC Power Supply Products are accessories that support the IP/analog fiber and EthernetConnect products. These accessories provide a range of options to provide power to fiber applications, power over copper (PoC) applications, and PoE applications. The 14-slot Rack Chassis allows for module installation in a chassis that is rack mountable. The chassis contains an internal 9 VDC, 6.5 A power supply that provides power directly to all modules installed in the chassis; no external power supply is required. The power supply provides current limiting at each slot for short circuit protection. The 9 VDC, 12 VDC, and 48 VDC Power Supply Products provide excellent voltage and current alternatives for powering stand-alone IP/analog fiber and Ethernet modules. The 48 VDC, 5 A and 10 A power supplies are ideally suited for PoE applications.
