certain components that must be proactively serviced to ensure proper functionality


  • Dramatically increased power system availability occurs as potential problems are corrected.
  • Increased mean time between failures (MTBF) is achieved when regular maintenance is performed by expert technicians.
  • Improved critical system reliability happens due to ongoing problem prevention.
  • Less unplanned downtime is possible due to regular oversight of a UPS and its critical components .
  • Lower total cost of service resulting from a maintenance progra.


  • Temperature check on all breakers, connections, and associated controls identifies hot spots that could lead to much larger problems.
  • Complete visual inspection of the larger power system helps uncover potential failures before they impact your business.
  • Component replacements are performed for equipment that has failed or shows signs of potential failure.
  • Factory Change Notices (FCN) are implemented to ensure your UPS is up-to-date and performing optimally.

Full Bank Capacitor Replacement

Your UPS systems use large capacitor banks made up of both DC electrolytic and AC polymeric film capacitors that degrade over time. Proactively replacing a full bank of capacitors is strongly recommended to achieve long service life and avoid unplanned downtime.
