True Online Double Conversion Technology for your Critical and non-Critical Power Loads

Common challenges our clients face with UPS Systems

  • Power capacity sizing to ensure the proper UPS is selected for your load(s)—common system failures we’ve seen stem from inadequate or incomplete inrush current specifications on equipment loads
  • High maintenance costs that are already too high and continue to rise, driven by short VRLA replacement cycles
  • Smaller footprint or different form-factor driven by the need to save rack space and/or floor space
  • System failures resulting in downtime due to various potential factors
  • Higher rack density requiring larger backup power kW capacity, in the same footprint or form factor
  • Redundancy requirement changes from N to N+X to 2N or greater

Maximizing Usability Features

Nickel-Zinc Battery Chemistry Support

  • Our UPS systems are one of the first available on the market to accommodate advanced Nickel-Zinc (NiZn) battery technology [manufactured by ZincFive]
    1. Lower total cost of ownership (TCO) with up to 4x longer battery life cycle (up to 20 years vs. ~5 years for VRLA)
    2. Safety benefits include being non-flammable, fail-safe, fully recyclable
    3. Rapid discharge applications are ideal, as NiZn batteries retain thermal stability while maintaining a fast recharge capability
    4. High energy density allows for NiZn battery’s weight to be less than half that of a comparable capacity VRLA battery

ETERNA UPS with Integrated Batteries

  • Save floorspace by having the battery string in the same overall enclosure as the UPS
  • Fast deployment and reduced labor costs with pre-installed and tested UPS + Battery systems that arrive ready-to-go, only requiring external cable hookups
  • Easy battery maintenance with slide-out battery drawers, insulated busbar connections and integrated DC disconnect breaker

High Efficiency

  • Up to 98% utilizing ECO Mode (Normal Double-Online Conversion Mode achieves up to 93% Efficiency)
  • Smart Sleep function—ability for system to intelligently shut down certain power modules when there is a lower load to increase total load rate over active modules, achieving higher efficiency

High Density + Modular + Redundant + Scalable

  • Integrated rectifier + inverter in each power module improves reliability with reduced points of failure
  • Hot-swappable power modules for simplified maintenance and low mean time to repair (MTTR)
  • Parallel functionality of all individual power modules in each system making each system inherently N+X redundant
  • Built-in system parallel controllers enable multiple UPS systems to parallel together to increase capacity, share a common battery string, and achieve 2N (or greater) redundancy from a single power source— all while ensuring automatic load sharing between power modules

Comprehensive Monitoring & Maintenance Management

  • Multiple internal temperature sensors for thermal abnormality detection in power modules (external Battery and Ambient Sensors also included)
  • Critical waveform recording for analysis of faults
  • Capacitors and fans runtime monitoring
  • Intelligent battery management for extending battery life and reducing maintenance as the UPS automatically applies boost or float charge, utilizes temperate sensors to avoid over and/or under charge, and adjusts the cut off end-of-discharge voltage according to load capacity
  • Self-aging function allows for simulation of various load conditions for testing, utilizing only 10% utility power relative to simulated load.
