Data Center UPS Systems
Modern data centers need uninterruptible power that delivers scalability, redundancy, efficiency, and predictable runtime. Whether you’re protecting an edge site, an enterprise server room, or a full data hall, UPS architecture is foundational to uptime.
Xtreme Power designs modular single- and three-phase UPS systems for mission-critical data center applications — from per-rack protection to multi-hundred-kilowatt deployments. Edge data centers carry different design considerations than centralized facilities; explore UPS for Edge Data Centers.
Centralized vs distributed vs rack-level UPS
One source for the facility
Large three-phase systems protect the entire facility, typically paired with VRLA battery strings. Common in legacy enterprise environments.
Protection by zone or row
Multiple UPS systems support zones or rows, improving redundancy and scalability. Widely used in colocation and modular deployments.
Power inside the rack
UPS integrated directly within the rack for high-density compute and edge environments — eliminating single points of failure and aligning with AI and GPU infrastructure trends.

Match the platform to the architecture
Integrated UPS, batteries, bypass, and distribution in a single 13U footprint. Built for high-density compute and rack-level deployments.
Scales for large enterprise and colocation deployments with flexible external battery configurations across the 480V / 400V class.
Integrated lithium UPS with internal LiFePO₄ batteries — engineered to cut footprint, maintenance, and lifecycle cost versus legacy systems.
Scalable three-phase platform (M90U-80 and M90U-140) with hot-swappable 15/20 kW power and battery modules, full wrap-around maintenance bypass, and N+1 redundancy — in an industry-leading footprint that saves up to 40% of floorspace.
Lithium or lead-acid
Longer life, higher temp, less maintenance
Longer service life, higher-temperature operation, and reduced maintenance in a smaller footprint.
Lower upfront cost
Lower initial cost, but requires more space, more maintenance, and periodic battery replacement over the system’s life.
What drives the right architecture
When to move beyond centralized UPS
Rack-level and modular UPS designs are increasingly preferred for high-density compute, improved fault isolation, and incremental scalability. They also reduce distribution losses and eliminate large battery rooms.
