  • LiFePO₄ Battery Chemistry with Dual Redundant BMS: Engineered with high-durability lithium iron phosphate cells that provide up to a 15-year service life (3,000–5,000 discharge cycles) and protected by dual redundant Battery Management Systems for cell balancing and overload control.
  • 208–240V Online Double-Conversion Topology: Designed for higher-voltage global operations, continuously regenerating AC power with pure sine wave output and zero transfer time during outage events.
  • 50°C (122°F) High-Temperature Rating: Formally rated to operate safely in harsh ambient environments up to 50°C.
  • Flexible 2U Convertible Design with IEC Outlets: Versatile 2U chassis with international IEC C13/C19 receptacles that can be mounted as a rack, tower, or wall-mounted.
  • Fast 1.5-Hour Recharge & Easy-Replace Internal Pack: Features LCD-adjustable charging (up to 8 A) that recovers batteries to 90% capacity in approximately 1.5 hours, alongside hot-serviceable battery access and optional XBDM bypass compatibility.
  • Substantially Lower Total Cost of Ownership (TCO): Operating up to four times longer than standard VRLA lead-acid UPS units, the 15-year battery life eliminates routine replacement cycles and field service visits across global multi-site infrastructure.
  • Total Power Conditioning for High-Voltage Equipment: Complete isolation from voltage sags, spikes, noise, and frequency fluctuations protects sensitive 208–240V IT, AV, and telecom hardware with zero power gap.
  • Uncompromising Reliability in Non-Conditioned Spaces: Provides dependable backup performance in hot, uncooled network closets, industrial enclosures, and telecom nodes without suffering the rapid battery degradation typical of lead-acid units.
  • Fast Outage Recovery & Zero-Downtime Maintenance: Rapid 1.5-hour recharge ensures quick system recovery between power drops, while the easy-replace battery pack and maintenance bypass options allow technicians to swap batteries without dropping critical loads.
  • Standardized Global Deployment: TAA compliance combined with global 208–240V IEC support allows enterprise IT teams to deploy a single, consistent, low-maintenance UPS platform across international locations.
