Product Description
Key Features & Benefits
-
Variable Module Management System (VMMS): Optimizes efficiency at low load levels by selectively placing unnecessary UPMs on “ready-state,” forcing the remaining modules to operate at their highest efficiency point.
-
Energy Saver System (ESS): Enables the UPS to reach 99% efficiency while maintaining the ability to transition to double-conversion mode in less than 2ms if it detects a power anomaly.
-
Field-Upgradeable Scalability: The 275kVA modules can be added to existing 9395 frames, allowing you to scale your capacity from 275kVA to over 1MVA without replacing the entire infrastructure.
-
HotSync® Load Sharing: Eaton’s patented technology allows parallel modules to share the load without the need for a master control wire, eliminating a common single point of failure.
-
Advanced Battery Management (ABM): Uses a three-stage charging cycle to prevent battery overcharging and extends the service life of VRLA batteries by up to 50%.
-
User Interface: Features a 10-inch color touchscreen display that provides intuitive access to detailed status information, performance metrics, and event logs.
