Xtreme – E91- 40000 – 40 kVA – Three Phase Online UPS

Xtreme Power E91 40 kW UPS — 208/120V Three-Phase, Unity Power Factor

The Xtreme Power E91 30 kW Series delivers robust three-phase, true online double-conversion
power protection for edge facilities, small data centers, network closets, and industrial control systems.
Available in 40 kW kW models at 208/120 VAC three-phase, the E91 provides
unity power factor (1.0 PF) output—supporting up to 25 % more real power than traditional 0.8 PF UPS
systems for today’s high-density IT loads.

With up to 94 % efficiency in online mode and 98 % in ECO mode, the E91 reduces energy and cooling
costs while maintaining continuous isolation from input disturbances. A 4.3″ color touch LCD gives at-a-glance
visibility into UPS status, alarms, and an interactive one-line diagram. External battery cabinets are available
to extend runtime, and the no rear service clearance requirement means the unit can be installed flush
against a wall—saving valuable floor space in tight equipment rooms.

Key Features & Benefits

• Unity Power Factor (1.0 PF) — Delivers full real-power capacity to support high-density IT and industrial loads.
• True Online Double Conversion — Provides continuous, clean output power regardless of input voltage or frequency disturbances.
• High Efficiency — Up to 94 % in double-conversion mode and 98 % in ECO mode to lower operating costs.
• Rear Clearance Not Required — Designed for front-only service, enabling installation directly against a wall.
• 4.3″ Color Touch LCD — Displays real-time UPS status, alarms, and one-line power flow in an intuitive interface.

At-a-Glance Specifications

Why E91 30–40 kW? The E91 30 kW and 40 kW models deliver the same enterprise-grade reliability and efficiency
as the smaller E91 family, while adding higher capacity and a space-saving, front-service design that fits tight
electrical rooms. Ideal for mission-critical edge and industrial applications needing true online protection, unity
power factor output, and maximum serviceability in constrained spaces.
