400-V UPS configuration offers highest efficiency for powering data centers
The Energy Saver System version of the 9390 and 9395 UPSs are available in 400-Vac UL-listed configurations and use a transformer-free design that delivers 99% efficiency. The UPS operates at this high efficiency unless utility power conditions force the UPS to work harder to maintain clean power to the load.
The Energy Saver System operates in any of four modes, depending on the conditions, including standard mode, double-conversion mode, high-alert mode, and storm-detection mode. It continuously monitors incoming power conditions and balances the need for efficiency with the need for protection. When power conditions are within acceptable limits, the UPS operates as a high-efficiency, energy-saving system—providing surge protection for IT equipment and ensuring clean power is delivered to the facility. If input power falls outside of preset tolerances, the UPS continuously provides power to the load, while conditioning the power to eliminate any disturbances. In this mode, the UPS processes incoming power through a rectifier and inverter, isolating IT equipment from the incoming ac source. If input power is outside the tolerances of the system, the UPS draws power from available battery modules or other standby sources. In configurations with a generator, the UPS ensures that generator power has stabilized before engaging the system. (Call 800-356-5794 for price and availability.)
