10–60 kW · 400/230V Three-Phase · Eaton BladeUPS Replacement

M90Ci-6S vs Eaton BladeUPS (400V)

The Xtreme Power M90Ci-6S and Eaton BladeUPS are modular online double-conversion UPS platforms for 400/230V three-phase applications in data center, healthcare, telecom, and industrial environments. Eaton has discontinued the BladeUPS (end-of-life October 1, 2023, with parts and service through Q3 2028), so most evaluations are replacement decisions. The M90Ci-6S is an active, current-generation platform that preserves a familiar 400V modular architecture as a like-for-like replacement, with assured long-term availability.

Specifications based on publicly available manufacturer documentation; confirm against current vendor data. Eaton lists the BladeUPS as discontinued (end-of-life October 1, 2023; service and parts through Q3 2028), with the 93PX positioned as its successor. The M90Ci-6S is an active, current-generation replacement preserving a familiar 400V modular architecture.

Where each fits

Choosing between them

The BladeUPS is discontinued, so this is primarily a replacement decision. The M90Ci-6S is an active, current-generation 400V modular platform that preserves a familiar architecture and deployment model while restoring long-term support and parts availability. On core electrical specifications the two are closely matched; the decision turns on platform lifecycle and support rather than raw performance.

Choose the M90Ci-6S if you need

  • An active, fully supported 400V modular UPS platform
  • A like-for-like replacement for an end-of-life BladeUPS
  • A familiar 10-60 kW three-phase modular architecture
  • Flexible internal or external (M90Ci-BC7) battery expansion
  • Long-term parts and service availability

The Eaton BladeUPS may remain in service if you have

  • An existing BladeUPS deployment maintained short-term (parts through Q3 2028)
  • A site standardized on the BladeUPS bus-bar and rack architecture
  • No near-term refresh planned before end-of-service
Questions

Frequently asked questions

Is the Eaton BladeUPS discontinued?

Yes. Eaton placed the BladeUPS at end-of-life as of October 1, 2023, with service and replacement parts available through Q3 2028 or until inventory is depleted. Eaton positions the 93PX as its successor. The M90Ci-6S is an alternative like-for-like 400V modular replacement.

Is the M90Ci-6S a direct replacement for a 400V BladeUPS?

Yes. The M90Ci-6S is a 400/230V three-phase modular online UPS spanning 10-60 kW, matching the BladeUPS voltage, topology, and modular deployment model, so it fits the same rack-based 400V environments.

What about battery runtime expansion?

The M90Ci-6S supports internal modular batteries up to 30 kVA and external expansion through the M90Ci-BC7 modular battery cabinet. The BladeUPS supports internal modules, extended battery modules, and external battery connection on 400V systems.
