The APC Line R is a microprocessor controlled tap changing power conditioner, which automatically corrects brownouts and overvoltages, and stabilizes chronic line voltage variation. Line R also provides multi stage surge suppression and full time EMI/RFI filters to handle all the problems your equipment is likely to face. A voltage meter on the Line R's front panel displays the relative input voltage level and alerts you to low or high voltage conditions. Line R automatically performs self tests, and its "adaptive mode" also senses and corrects frequent tap changing, thereby reducing wear on the relays for a longer life span and quiet operation.

APC Personal SurgeArrest Notebook is a reliable power protection for Notebook computers, fax and answering machines. Protecting just the AC line for a notebook computer is not enough. Lightning or other damaging surges can enter and destroy your equipment through the phone line as well. The SurgeArrest Notebook Protector guarantees protection of both paths.

Lightning and power surges can permanently damage your audio and video electrical equipment. Even small surges can influence the performance of your electronics. APC Premium Audio/Video Surge Protector 11 Outlet with Splitter and Coax Protection unit will protect your valuable equipment from the threat of bad power.

APC ProtectNet Rack Mount Surge Protection Module make up an overwhelming majority of all surge induced damages where the equipment was thought to be already protected but had a back door such as a modem line unprotected. Network interface cards, in particular, can be destroyed by relatively mild spikes. According to Ethernet standards (IEEE 802.3), non-AC network electrical hazards include: direct contact between components and power or lightning circuits, static charge buildup on cables and component, high energy transients coupled onto the local cabling system (those induced by other cables which are installed in the general proximity of network cables or lightning within a mile radius) and potential differences (even from building to building, between safety grounds to which components are connected).
