Li90 10kVA — Compact Three-Phase Lithium UPS with Up to 45 Minutes Internal Runtime
The Li90 10kVA delivers full 10kW three-phase power with integrated LiFePO₄ batteries and up to 45 minutes of internal runtime in a 12.6″ slim cabinet — no external battery cabinets required. Designed for telecom rooms, small electrical spaces, and edge deployments where space, weight, and temperature constraints limit traditional UPS options.
Scalable runtime — 15, 30, or 45 minutes without external cabinets
The Li90 10kVA supports 1, 2, or 3 internal LiFePO₄ battery modules — each adding approximately 15 minutes of runtime at full 10kW load. Select the module count that matches your runtime requirement. All modules are hot-swappable and fit inside the UPS enclosure.
29 min at 5kW
58 min at 5kW
87 min at 5kW
This internal runtime capability is uncommon in compact three-phase UPS systems — competing 10kVA platforms typically require external battery cabinets to achieve more than short-duration backup. The Li90 integrates all runtime within the UPS cabinet itself.
Built for distributed and edge infrastructure
Continuous online double-conversion topology — the connected load never operates on raw utility power. No transfer delay during power events. Output is clean, regulated, and isolated from upstream disturbances.
Rated for reliable operation to 50°C (122°F). Suitable for telecom shelters, unconditioned electrical rooms, and industrial spaces where VRLA systems require supplemental cooling or derating.
Battery modules are replaced without tools and without powering down the load. The door opens, modules slide in and out. No maintenance window required. Up to 15-year LiFePO₄ service life.
Full-color touchscreen showing single-line mimic, phase voltages, frequency, and event log. Two communication slots for optional SNMP/Web management cards. Programmable dry contacts for facility integration.
Input, output, bypass, and maintenance bypass breakers integrated in the cabinet. Service the UPS safely without powering down the load. No external switchgear or bypass cabinet required.
Circuit boards are conformal coated for industrial and high-humidity environments. Self-cleaning fan system reduces maintenance and extends service life in dusty locations.
