Scalable 20 kVA UPS

The Eaton 9PXM12S20K-PD is a 20 kVA battery backup that scales to 20 kVA in an N+1 redundant configuration. It accepts hardwired 208-240 V AC input and fits a 21U rack or tower footprint. The unit targets data-centre and critical-infrastructure operators who need high-density power protection with room for growth.

Thermals noise and power draw

The 690 lb chassis uses forced-air cooling across a 34.5 in depth and 36.5 in height to manage heat at full load. Fan speed ramps with load percentage, so acoustic output rises only when the UPS is delivering near-rated power. Double-conversion topology keeps input current clean while the battery system carries the load during outages.

Outlet mix and compliance

Eight NEMA 5-20R, two L6-20R, two L6-30R and two L14-30R receptacles let you connect servers, networking gear and peripheral strips without adapter cables. FCC, ICES-003 and TAA markings simplify deployment in regulated environments. The hardwired input requires professional installation, so the unit is not suited for plug-and-play desktop use.

Questions about this item

How do I hardwire the 208-240 V AC input on this 21U rack/tower UPS, and what step is often missed?

Have a qualified electrician connect the supply to the unit's hardwired input terminals; the step often missed is verifying the branch-circuit breaker matches the 20 kVA rating before energising.

Which user-replaceable battery modules does the 9PXM12S20K-PD use, and how many are required?

It uses Eaton 9PXM battery modules; the scalable 12-slot frame requires up to 12 modules for full 20 kVA N+1 redundancy.

At 20 kVA load, what is the first limit reached — runtime, thermal, or outlet current?

The outlet current limits appear first: each L6-30R is rated 30 A, each L6-20R 20 A, and each 5-20R 20 A, so total connected load must stay within those per-receptacle ratings.
