Subj : Power Protection You Can Trust! To : All From : Bob Watson Date : Fri Dec 01 2000 06:49 am Posted: 12-01-00 Zero Surge - "Surge Eliminator" The power protector for LANS, PCS and COMPUTER PERIPHERALS Power surge. Your system's biggest threat. ------------------------------------------ No matter how sophisticated your system is, its power cord is its Achilles heel. Powerline surges occur all the time, constantly battering your computer installation. Big ones can seriously damage the equipment by overstressing or causing arc-overs inside tiny computer chips. Even small ones disrupt programs and alter data. Ordinary surge suppressors can't cope. They can even CAUSE problems, by diverting the surge into ground circuitry used by all modems and datalines and disrupting or damaging the integrity of the entire LAN system. That is why we invented our Surge Eliminator, the first real advance in surge protection technology for PCs, LANs and peripherals. No sacrificial components. -------------------------- Most surge protectors rely on components called metal oxide varistors (MOVs), which sacrifice themselves in service and wear out. Zero Surge protectors use none of these sacrificial components, and are immune to surge damage. A patented technology that eliminates surge. -------------------------------------------- Zero Surge's are not surge suppressors but surge eliminators - the result of a unique patented technology. So-called surge suppressors are actually surge diverters, channeling surges into ground lines. Zero Surge units employ unique patented series circuitry that intercept surges with zero response time, stores the surge energy, then gradually and harmlessly releases it to the neutral wire. They work like a bucket with a hole in it. So only with Zero Surge do the ground wires used for voltage reference by inter- connecting datalines remain undisturbed. And only with Zero Surge is the risk of damage or data contamination through the ground completely eliminated. Only Zero Surge stands directly in the line before the computer to intercept the surge, and is immune to damage by the most powerful surge. Pays for itself. ---------------- Zero Surge will yield a one-year payback if failure costs are reduced by only 1.3% for the average case reported by Infonetics, an independent research firm. Infonetics has reported that Fortune 1000 companies experience on an average 23.6 Local Area Network failures per year, with an average duration of 4.9 hours each, costing the average company $3.48 million per year. That's a heavy price to pay for using inferior power protection. Power surges are gaining increasing recognition as a major cause of computer disruption and failure. Eliminate them with Zero Surge.
