  • Rack-Integrated 6U Dual-Slot Architecture: Houses a full 208/120V three-phase online double-conversion UPS within a compact 6U rack chassis (featuring one power module and one battery module slot).
  • Unity Output Power Factor (PF 1.0): Delivers full real-power output (kVA = kW at both 5 kW and 8 kW configurations) with up to 98% efficiency in ECO mode (93% online).
  • Integral Maintenance Bypass Switch: Equipped with a built-in maintenance bypass switch directly on the unit chassis.
  • Modular & Phased Battery Expansion: Supports modular scaling by adding external battery modules (up to 8 battery modules per power module) without altering the core chassis or footprint.
  • Flexible Input/Output Connections & TAA Compliance: Offers hardwired terminal blocks or optional input line cords (L21-20P / L21-30P) and breaker-protected receptacle panels, fully compliant with TAA regulations (UL-1778 / cUL).
  • Eliminates Electrical Room Reconstruction: Brings centralized three-phase power continuity directly inside standard 19-inch IT racks or micro-data centers, saving valuable floor space and avoiding expensive facility redesigns.
  • Maximum Electrical Capacity Utilization: Unity power factor ensures you get 100% usable real wattage (5 kW or 8 kW) without forcing system oversizing, lowering utility and thermal cooling costs.
  • Zero-Downtime Maintenance Without Extra Panels: The integral maintenance bypass allows technicians to safely service or replace components without dropping downstream critical loads or buying costly external wall-mounted bypass switchgear.
  • Phased Investments & Customizable Runtime: Modular battery growth enables organizations to scale backup runtimes as power demands expand, matching precise operational requirements without replacing the core UPS.
  • Seamless Procurement for Federal & Healthcare Environments: TAA compliance and stringent certifications make it an ideal fit for regulated public sector deployments, VA medical modernization initiatives (e.g., EHRM), government labs, and defense IT rooms.
