J90i 1U Lithium Rack UPS – High-Density Online Double-Conversion (1000–3000 VA, 208–240V)
1000–3000 VA | 208–240V | 1U Online Double Conversion
High-density lithium rack UPS engineered for global IT, telecommunications, AV, and industrial infrastructure requiring conditioned power, compact deployment, and remote power control in 208–240V environments.
The J90i Series is a 1U online double-conversion UPS designed for higher-voltage rack environments where space efficiency, thermal performance, and operational control are critical.
By integrating Lithium Iron Phosphate (LiFePO₄) batteries within a compact 1U architecture, J90i enables long service life, high-temperature operation, and reduced maintenance while delivering conditioned power directly at the equipment rack.

J90i is designed for distributed infrastructure operating on higher-voltage single-phase systems common in global deployments.
It enables localized UPS protection at the rack level, reducing reliance on centralized UPS systems while supporting standardized deployment across international environments.
Online double-conversion topology ensures continuous conditioned power independent of upstream electrical disturbances, while lithium battery architecture reduces maintenance and improves performance in elevated temperature environments.
J90i operates as the rack-level continuity layer for 208–240V infrastructure within a distributed power architecture.
It is typically deployed:
- at the equipment rack for localized UPS protection
- across multi-site global infrastructure
- in telecommunications, industrial, and distributed IT environments
Within the Xtreme Power architecture:
