When an uninterruptible power supply (UPS) is operating at significantly under capacity, its energy efficiency can be negatively impacted. Xtra VFI mode is a smart way to minimize losses and improve efficiency when running in double conversion mode by dynamically adjusting the number of active modules to match the load.
Modules that are not needed are switched to standby but remain in state of readiness if the load increases. The efficiency improvements achieved by this mode of operation are especially significant when the load is less than 25 percent of full UPS system capacity.
