This table represents general guidelines for selecting the appropriate UPS based on minimum andtypical runtime estimates. A ‘maximum configuration’ load will result in ‘minimum’ UPS runtime.‘Typical’ loads are based on a production system running at approximately 70% of maximum capacity(based on the power delivered to the device from the power source, i.e., 70% of the value provided as amaximum equals the rating of the power supply). The ‘typical’ loads represent a more likelyconfiguration; therefore, they provide a more likely estimate of runtime. The values listed as typicalgenerally are equal to the rating of the power supply. Since power supplies operate at 70% of load, thesystem power supplies are actually operating at 70% of the values listed, though the power required fromthe source is what is listed. Customer environments are unique and are unlikely to be preciselyrepresented by any of the specific entries in the table.2. Power-Factor Corrected (PFC) power supply.313
