High-efficiency, space-saving three-phase UPS for edge facilities, small data centers, and industrial applications.

Category:

208 / 120 V Power Protection for Localized Infrastructure
30–40 kVA Centralized VRLA Architecture

The Xtreme Power Conversion E91 Series is a compact centralized three-phase online double-conversion UPS platform designed to support expanded facility infrastructure in healthcare, industrial, commercial, telecommunications, and distributed IT environments.

The integrated cabinet architecture with internal VRLA batteries and optional matching external battery cabinets supports predictable lifecycle maintenance planning and simplified deployment in electrical-room installations where modular scalability is not required but higher centralized capacity is needed.

Typical Deployment Environments

Three-phase UPS platforms in this capacity class are commonly deployed where facility infrastructure requires higher localized conditioned power protection without large centralized data-center UPS architecture.

Typical applications include:

  • Multi-room healthcare imaging suites
  • Industrial production lines and automation cells
  • Commercial building electrical infrastructure
  • Telecommunications aggregation nodes
  • Distributed IT and micro data center environments

These deployments typically prioritize centralized capacity density, predictable maintenance planning, and straightforward service accessibility.

Compact Centralized Three-Phase UPS Architecture

The E91 platform utilizes a compact centralized UPS cabinet architecture with integrated internal VRLA batteries to support simplified facility deployment and established lifecycle service models.

Optional matching external battery cabinets allow runtime expansion where infrastructure planning requires extended backup duration without transitioning to modular UPS architecture.

This architectural approach is commonly selected where infrastructure planners prioritize deployment predictability, electrical-room integration efficiency, and conventional lifecycle maintenance frameworks.

Platform Characteristics

  • Compact centralized three-phase UPS cabinet design
