Uninterruptible power supply can extend the power supply for a long time
UPS power backup delay time calculation method: (battery capacity X battery operating voltage) / equipment power = extended time (hours).
Backup UPS is generally built-in 4AH or 7AH battery, the backup time is fixed; online and online interactive UPS built-in 7AH battery standard models, but also with large-capacity battery with long-term models, the user can To achieve the backup time to determine how much capacity with the battery.
UPS spare time is determined by the UPS energy storage device, and now the UPS are generally sealed with a maintenance-free lead-acid batteries as energy storage devices, the size of the battery capacity by the "number of hours (AH)" this indicator , Which means the time at which the discharge is performed at a predetermined current. The same voltage of the battery, the large number of hours of large capacity; the same number of hours of the battery, the high voltage capacity, usually in terms of voltage and the number of hours together the battery capacity, such as 12V / 7AH, 12V / 24AH, 12V / 65AH, 12V / 100AH.
