27A battery

Determination of UPS uninterruptible 27A battery discharge time

After the mains power outage, UPS relies on battery energy storage to supply power to the load. Standard UPS has its own built-in battery, which can generally continue to supply power for several minutes to tens of minutes after the power outage; while long-term UPS is equipped with an external battery pack, which can meet the user's need to continue to supply power during a long power outage. Generally, the full-load configuration time of long-term UPS can reach more than several hours.

Generally, the backup time of long-term UPS is mainly limited by factors such as battery cost, installation space size and battery recharge time. Generally, UPS and generator are used in areas with poor power environment and frequent power outages. When the power outage occurs, the UPS is first powered by the battery for a period of time. If the power outage is long, the backup generator can be started to continue to power the UPS, and then switch to the mains power supply when the mains power is restored.

Battery power supply time is mainly affected by factors such as load size, battery capacity, ambient temperature, and battery discharge cut-off voltage. For the battery power supply time of general computer UPS, the battery discharge current can be calculated first, and then the discharge time can be checked according to the battery discharge curve. The battery discharge current can be calculated according to the following empirical formula:

Discharge current = UPS capacity (VA) × power factor / (average battery discharge voltage × efficiency)

If you want to calculate the battery discharge time under actual load, just replace the UPS capacity with the actual load capacity.
