Scalable 8 kVA UPS

The Eaton 9PXM12S8K-PD is a new 8 kVA uninterruptible power supply 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. This unit suits data-centre racks and critical infrastructure needing expandable, fault-tolerant backup power.

Outlet mix and headroom

Four NEMA 5-20R, two L6-30R, two L6-20R and two L14-30R outlets distribute power to varied IT loads. The 8 kVA base capacity handles typical rack densities, while the modular architecture adds headroom up to 20 kVA when extra power modules are installed. Redundant N+1 operation keeps systems running during a module failure.

Thermals noise and draw

The 378 lb chassis occupies 34.5 by 17.5 by 36.5 inches and meets TAA, FCC and ICES-003 compliance. Forced-air cooling manages heat in normal rack environments; acoustic output is typical for a 21U hardwired UPS. Input current scales with load up to the 240 V rating, so plan branch circuits accordingly.
