After the mains power failure, Santak UPS power supply relies on battery energy storage to supply power to the load. The standard UPS itself has its own battery, which can generally continue to supply power for several minutes to tens of minutes after a power failure; The long-lasting UPS is equipped with an external battery pack, which can meet the user’s needs of continuous power supply during a long-term power outage. Generally, the full-load configuration time of the long-lasting UPS can reach more than several hours. When the battery is powered, it is mainly affected by factors such as load size, battery capacity, ambient temperature, and battery discharge cut-off voltage. For general computer UPS battery power supply time, you can first calculate the battery discharge current, and then investigate and deal with the discharge time according to the battery discharge curve. The battery discharge current can be calculated according to the following empirical formula:
Discharge current = UPS capacity (VA) x power factor/(battery discharge average voltage x efficiency)
If you calculate the battery discharge time under actual load, you only need to exchange the UPS capacity for the actual load capacity.
Generally, the backup time of long-lasting UPS is mainly limited by factors such as battery cost, installation space, and battery recharge time. Generally, UPS and generator are used to supply power in areas with poor power environment and frequent power outages. When there is a power outage, the ups is first powered by the battery for a period of time. If the power outage lasts for a long time, you can start the backup generator to continue to supply power to the Santak ups power supply, and then switch to the mains power when the mains power is restored.
