The power supply time factor of an online APC UPS power supply after a power outage is very simple, which is the battery. The larger the battery capacity, the longer the power supply time, and the battery is the energy storage device. The larger the battery capacity, the longer the battery can supply power to the device.
The duration of time an online UPS power supply provides to a load is mainly determined by factors such as the load power of the UPS power supply by the load device and the total battery capacity of the UPS power supply. If a longer amount of power is required from the UPS power supply, the number of batteries in the UPS power supply should be increased accordingly. In fact, the longer the power provided by UPS power supply, the better. The main reason is that high-power UPS power supply, with a longer backup time, can result in hundreds of batteries supplying power, thereby forming a series parallel connection of multiple groUPS of batteries. And each battery, relative to the entire system, is a faulty unit, so it is best not to blindly pursue long-term use.
