Eaton announced the Eaton 9390 and Eaton 9395 uninterruptible power systems (UPS) in 400-V UL-listed configurations. These systems allow consulting-specifying engineers and customers in North America the ability to recognize significant energy savings and efficiency gains while employing proven technologies and architectures. Of the several alternative power distribution systems currently found in the U.S. and Canada, 400 Vac and 600 Vac systems are generally accepted as the most viable. While the 400-V power scheme is common in Europe, the Middle East and Asia (EMEA), Eaton is the first to offer this configuration with UL approval in North America. Continuing its legacy of innovation with three-phase UPS technology, Eaton leveraged the transformer-free design of the 9390 and 9395 systems to provide a 400 Vac solution specifically for North American markets.
