Description: Value which denotes which Power Strategy is currently set for the UPS. The values are: highAlert(1) - The UPS shall optimize its operating state to maximize its power-protection levels. This mode will be held for at most 24 hours. standard(2) - Balanced, normal power protection strategy. UPS will not enter HE operating mode from this setting. enableHighEfficiency(3) - The UPS is enabled to enter HE operating mode to optimize its operating state to maximize its efficiency, when conditions change to permit it (as determined by the UPS). forceHighEfficiency(4) - If this value is permitted to be Set for this UPS, and if conditions permit, requires the UPS to enter High Efficiency mode now, without delay (for as long as utility conditions permit). After successfully set to forceHighEfficiency(4), xupsTopoPowerStrategy changes to value enableHighEfficiency(3). xupsOutputSource will indicate if the UPS status is actually operating in High Efficiency mode.
