The AV550SC Backup Power Block provides the highest level of protection for structured cabling installations (ie. telephone, Internet and coax connections). With reliable battery backup, surge protection and EMI/RFI line noise filtering, the AV550SC provides a complete protection solution for audio/video distribution systems by supporting modems, routers, RF amplifiers, network interfaces, cameras, modulators and other equipment through all power problems. In the event of a power failure, the AV550SC includes an auto-restart feature that eliminates the need to perform an on-site restart. In addition, when a modem or router freeze-up occurs, the AV550SC features a recycle/reset button with sequential outlet startup for proper modem and router rebooting.
