Eaton 93PR UPS – Features


  • Maximum double conversion efficiency
    The 93PR offers the highest double conversion efficiency in the market, reaching above 96%.
  • Optimised double conversion efficiency - Variable Module Management System (VMMS)
    VMMS can optimise the load levels of power modules in a single 93PR UPS or in parallel systems, by suspending extra UPS capacity.
    This means not only greater efficiency at lower load levels, but optimum efficiency at all load levels.
  • Energy Saver System delivers superior > 99% efficiency
    Energy Saver System enables > 99% efficiency across the UPS operating range. In ESS, load is powered securely through static bypass line with double conversion available on-demand with typical 2 ms transition time in the event of any abnormality on supply source. When operating in ESS mode, load is protected with inherent surge suppression.
  • Hot swappable and hot scalable
    The 93PR’s power module can be replaced or added while another module continues protecting the load.
    This eliminates the need to go to bypass for module replacement or upgrading (MTTR: 0 minutes). 
    Replacement and upgrade (N+1) operations typically take less than 10 minutes.
  • Easy management
    The 93PR provides easier access to detailed status information through its large, user-friendly 7” LCD touchscreen interface.
    With the 93PR’s graphical LCD interface you can track statistics on energy savings, battery time, outage tracking, load profiling and much more. The green/yellow/red LED light-bars make system status visible from a distance in data centres.
  • Advanced battery management
    Unique charging algorithm prolongs battery service life significantly compared to traditional charging methods. 
    Automatic battery tests ensure any defects on batteries are detected and failed blocks replaced on time. 
    Battery health data is available for viewing easily through the display. Being able to monitor the condition of batteries and history log of test data, system maintenance can be better planned and scheduled ahead.
