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.
Each LiFePO₄ module is 50 Ah / 57.6 V / 2,880 Wh · 80 lbs · hot-swappable without powering down the load.
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
Online double-conversion
Continuous online topology with zero transfer time — the load never operates on raw utility power, and output stays clean, regulated, and isolated from upstream disturbances.
50°C operation — no cooling dependency
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.
Hot-swappable battery modules
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.
4.3″ touchscreen with SNMP monitoring
Full-color touchscreen showing single-line mimic, phase voltages, frequency, and event log. Two communication slots for optional SNMP/Web cards. Programmable dry contacts for facility integration.
Full breaker design — maintenance bypass
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.
Conformal-coated PCBs · smart de-dust fans
Circuit boards are conformal-coated for industrial and high-humidity environments. The self-cleaning fan system reduces maintenance and extends service life in dusty locations.
