Eaton 9PXM UPS Frame, 4-20 kVA (N+1), Hardwired Input, Hardwired Output, Rack/Tower, 21U, Online/Double-Conversion, Free Standing Model, Black/Silver, 110V/220V, 120V/208V, 120V/240V, 127V/220V

The Eaton 9PXM12AAAAA is a power backup platform that uses a modular architecture to deliver uninterruptible power for loads between 4 and 20 kilovolt amperes. It is built for organizations that cannot afford a single second of downtime, whether that means a growing data center, a hospital imaging suite, or a factory automation line.

The frame accepts multiple hot-swappable power and battery modules, so you can add capacity or replace components while the connected equipment keeps running. This design also enables N+1 redundancy; if one module fails or is removed for service, the remaining units continue to carry the full load.

Clean, stable electricity comes from the online double-conversion topology, which isolates sensitive electronics from blackouts, brownouts, surges, and frequency variations. Eaton’s ABM charging algorithm monitors each battery string and adjusts charge cycles, a process that extends battery life by up to fifty percent and provides early replacement warnings.

The system arrives with hardwired input and output terminals that accommodate common voltage arrangements such as 110/220, 120/208, 120/240, and 127/220 volts. Two Mini-Slot bays support optional network, Modbus, or relay cards, allowing you to tie the UPS into building management systems or Eaton’s Intelligent Power Software Suite for remote monitoring and automated shutdown.

Deployment is straightforward. Install the chassis as a free-standing tower in a wiring closet, or slide it into a standard rack where it occupies 21U of space. Either way, front-access service points simplify maintenance, and an operating temperature range up to 40 °C keeps the unit comfortable in most controlled environments.
