The Eaton 9PX lithium-ion UPS, available in rackmount and tower forms, guarantees an extended 8 to 10 years of life for both the UPS and batteries. With power ratings from 1 to 6 kVA, it accommodates low and high voltage preferences and supports up to four external battery modules for extended runtime. This lithium-ion UPS retains the reliable features of the lead-acid version, including load segments for prioritized shutdowns, remote power control options, and output relay ports for increased control capabilities.
