The UPS sets the standard for the next generation of UPS progress with advanced features such as its transformer-free IGBT converters that include three-level topology and interleaving controls to enable market- leading efficiency of 97.6 per cent. It also supports Xtra VFI, which further minimises power consumption by intelligently configuring the number of modules required to support the current critical load. When Xtra VI is enabled, the number of active modules required will adjust accordingly, with modules not needed switching to a standby state of readiness but primed to become active again if the load increases. 33

The battery plays a key role in the overall reliability and availability of a power protection system. It supplies the energy required by the critical load in the event of a mains utility failure or when the input mains voltage and frequency are outside the acceptable values. Moreover, the battery represents an important share of the total cost of the UPS, and therefore battery care and management are of paramount importance when a UPS is designed. Kohler Uninterruptible Power provides a range of remote monitoring and diagnostics services to provide early fault detection and prevention.
