Double conversion topology. The Eaton 9E constantly monitors power conditions and regulates voltage and frequency due to the online double conversion topology. Get clear information on the UPS status and measurements (load level, battery level, input/output voltage and frequency) on a single screen with the new LCD interface. Integrate 9E into all software environments. The Eaton 9E is delivered with Eaton’s Intelligent Power Software and is compatible with all major OS including advanced integration in VMware vCenter and Microsoft Hyper-V. The internal bypass allows service continuity in case of an internal fault. A maintenance bypass is also available as standard for easy maintenance of the UPS without powering down critical systems. Extend runtime as you like by adding up to 4 external battery modules (EBM).
