Lithium UPS Systems
All Xtreme Power lithium UPS systems use LiFePO₄ (lithium iron phosphate) battery chemistry — 350VA to 30kW, single-phase and three-phase. Find the right platform below by form factor.
Compact and Embedded Lithium UPS
The thinnest UPS in the Xtreme Power line. Mounts behind kiosk displays, on DIN rails inside control panels, or flat on any surface. No fan — silent in public-facing environments. No battery replacement for the life of the deployment.
1U short-depth form factor for shallow wall-mount cabinets, structured wiring enclosures, and IDF installations where standard rack UPS depth won’t fit. Same LiFePO₄ chemistry — no routine battery replacement.
1U Online Lithium UPS
Online double-conversion, switchable outlets, remote reboot capability, high-temperature operation to 50°C. The 2kVA and 3kVA models carry extended battery capacity for longer runtime at typical network loads — often eliminating the need to step up to a tower UPS.
Same platform as the J90 — online double-conversion, switchable outlets, remote reboot, 50°C operation — at 208V/230V for international and commercial deployments. J90i for global infrastructure standardization.
Rack and Tower Online Lithium UPS
Online double-conversion in a convertible rack/tower form factor. Higher capacity than the 1U J90 for larger loads or extended runtime requirements. LiFePO₄ battery eliminates replacement across distributed deployments.
Same platform as the P91Li at 208V/230V for commercial and international deployments. Convertible rack/tower form factor. Online double-conversion with LiFePO₄ battery chemistry.
Three-Phase Lithium UPS
Three-phase online UPS with internal LiFePO₄ batteries. Supports 1–3 hot-swappable battery modules. Up to 87 min at 5kW load (3 modules).
Three-phase online UPS with internal LiFePO₄ batteries. Requires 2–3 hot-swappable battery modules. Up to 22 min at full 20kW load (3 modules).
Three-phase online UPS with internal LiFePO₄ batteries. Requires 3 hot-swappable battery modules. Up to 15 min at full 30kW load. Highest capacity Li90 model.
