Why the M90C

Why choose the Xtreme Power M90C?

Unity power factor

kVA = kW — full system utilization, no wasted power.

Universal slot flexibility

Each slot accepts a power module or a battery module — a working system always needs at least one power module and one battery module.

Modular & scalable

Hot-swappable design enables fast, cost-effective maintenance and capacity upgrades.

Continuous protection

Engineered for data centers, telecom, edge computing, and industrial applications.

Flexible installation

Easily configure redundancy, runtime, and output distribution.

TAA compliant

Eligible for US government and public-sector applications.

High energy efficiency

Lower operating costs and reduced total cost of ownership.

Remote monitoring

Communication slot for Web/SNMP and Modbus — monitor and manage over the network.

FAQ

Frequently asked questions

What voltage range does the M90C support?
Both 208/120V and 400/230V three-phase, depending on model. The M90C Series covers 5–24 kVA at 208/120V; the M90Ci Series covers 10–60 kVA at 400/230V.
Can the M90C be rack-mounted?
Yes. The M90C-2S and M90Ci-2S are rackmount-ready out of the box. The larger M90C-6S and M90Ci-6S are rack-mountable with the optional M90C Rack Mount Kit, which includes ramps, rails, and mounting hardware.
Is the M90C a good replacement for Eaton BladeUPS systems?
Yes — the M90C is a drop-in replacement for the Eaton BladeUPS, offering hot-swappable modular design, unity power factor, higher efficiency, and full scalability from 5 kVA to 60 kVA.
What line-cord and receptacle options are available?
M90C-2S units offer optional factory-installed connections: 5 kVA models use an L21-20P line cord and L21-20R receptacle panel; 8 kVA models use an L21-30P line cord and L21-30R receptacle panel. These reduce setup time and ensure compatibility with standard three-phase power.
Can I expand the runtime of the M90C?
Yes. The M90C-2S provides up to ~12 minutes at full load, while the M90C-6S extends to up to ~5 hours at full load with the BC7 battery cabinet. Runtime expands with modular battery cabinets such as the M90S-BC7, M90-BC, or M90BCi-7, depending on model, and hot-swappable battery modules allow runtime expansion without downtime.
