How Long Will a UPS Run During a Power Outage?

Introduction UPS runtime is not a single fixed number. The amount of time a UPS can operate during an outage depends on several variables. The Main Factors Connected Load Higher load generally means shorter runtime. Battery Capacity Larger battery configurations can provide longer runtime. Battery Condition Older or degraded batteries may provide less runtime than new batteries. External Battery Cabinets Compatible external battery cabinets can significantly extend runtime. Example A GXT5 system can have substantially different runtime at 50% load compared with 100% load. Therefore, asking “How many minutes does this UPS provide?” without specifying the load can be misleading. Final takeaway Provide your expected load when asking Power Icon for a runtime recommendation.

How to Choose the Right UPS Capacity for Your Equipment

Introduction UPS capacity is commonly expressed in VA and watts. Choosing a UPS solely because its VA rating appears sufficient can be a mistake. The connected load and required operating margin also matter. Start With Your Load Identify the equipment that needs protection and determine its expected power consumption. Consider VA and Watts VA represents apparent power while watts represent real power consumption. The relationship between the two is affected by power factor. Allow Appropriate Capacity Avoid selecting a UPS that operates permanently at its maximum capacity. A suitable operating margin can provide additional flexibility for changing loads. Consider Runtime If backup runtime matters, battery capacity and external battery options should also be evaluated. Final takeaway Tell Power Icon your equipment and load requirements rather than selecting a model based solely on its headline capacity.
