  • LiFePO₄ (Lithium Iron Phosphate) Battery Architecture: Engineered with high-durability lithium iron phosphate cells providing up to 15 years of battery service life or 3,000–5,000 discharge cycles.
  • Online Double-Conversion Topology: Delivers continuous power conditioning, pure sine wave output, and zero transfer time during outage events.
  • 50°C (122°F) High-Temperature Operation Rating: Designed to function reliably in extreme ambient thermal environments up to 50°C.
  • Lightweight 2U Convertible Design with Short-Depth Option: Features a 2U chassis that is roughly 30% lighter than lead-acid equivalents, mountable as a rack, tower, or on a wall—including an ultra-shallow 10.6-inch deep 1000 VA model.
  • Fast Recharge & Integrated BMS with Hot-Swappable Pack: Recharges internal batteries to 90% in approximately 1.5 hours and includes a Battery Management System (BMS) with hot-swappable battery support.
  • Eliminates Battery Swaps & Lowers TCO: Operating up to four times longer than traditional VRLA lead-acid batteries, it eliminates routine battery replacements and field maintenance visits for up to 15 years.
  • Total Power Isolation for Mission-Critical Loads: Completely shields downstream network, server, and AV hardware from utility spikes, line noise, and sags without any millisecond power interruption.
  • Uncompromising Reliability in Unconditioned Spaces: Functions safely in hot, non-conditioned spaces—such as crowded telecom rooms and uncooled network closets—without rapid battery degradation.
  • Flexible Placement in Restricted Spaces: The lightweight footprint and short-depth chassis options allow easy installation into shallow rack cabinets, wall-mount enclosures, and space-constrained IT closets.
  • Rapid Outage Recovery & Reduced Service Downtime: Fast 1.5-hour recharge times ensure the system quickly regains full backup capacity between recurring power drops, while hot-swappable packs allow battery maintenance without taking connected equipment offline.
