• Battery configuration choices to optimise UPS reliability
  UPS battery systems perform a vital role during mains power interruptions, but the choice of configuration could potentially lead to single points of failure. By using multiple strings of parallel batteries, and different interconnections between batterie

• Battery protection and maintenance - critical to your UPS operation
  These expensive components can have their lifetime severely threatened by elevated temperatures, excessive discharge - recharge cycles and sudden load changes. Read how to provide protection from these and other events.

• Comprehensive and effective isolation of UPS loads
  How fully redundant electronic DC protection (EDCP) systems can eliminate the possibility of DC component propagation.

• Managing the power demand of leading power factor blade servers
  How modern transformerless UPSs can handle leading power factors far more efficiently than legacy installations, as well as bringing other efficiency and space benefits.

• Maximising availability in power protection systems
  How modular UPS offers the highest availability in the market today, with all components, including the batteries, being redundant and hot-swappable.

• Optimising availability in parallel redundant UPS systems
  A Kohler PW modular UPS can achieve an availability of 0.9999990 compared with an earlier norm of 0.9999952 - a very significant improvement by reducing repair time from around six hours to just half an hour.
