Bridges, data switches, hubs, routers, and telephone systems now comprise an "enterprise" system, and these sensitive devices require clean, continuous AC power to ensure data integrity, hardware stability, and maximum equipment life. To ensure optimum performance with all types of electronic equipment, every Enterprise Series UPS produces a continuous, true sinewave output that these sensitive, mission-critical devices demand. An Enterprise UPS keeps vital equipment up and running in spite of utility power fluctuations or failures. When incoming utility power falters, your Enterprise Series UPS automatically conditions and stabilizes the sinewave to provide the clean AC power required by critical electronics. MINUTEMAN"s powerful Double Buck and Double Boost voltage regulators handle the majority of the line conditioning workload while MINUTEMAN"s Independent Battery Bypass topology ensures that, even if the UPS battery becomes discharged or disconnected, the Enterprise UPS continues to condition the incoming AC power and correct every electrical anomaly short of a complete loss of power. Should AC power fail altogether, Enterprise units switch to battery backup in 1.8 milliseconds - about twice as fast as competitors" models. Adding optional Enterprise external battery packs backs up your systems for an unlimited length of time.The MINUTEMAN Enterprise E 1100i is a 1100VA/660W 230 VAC true sinewave, extended runtime UPS designed for desktop, tower, wall, or 2U high rackmount (19 or 23 inches) configurations. 23-inch rack and wallmount installations require the optional rack and wall kit.
