Schneider UPS power supply system principle and power supply time

The function of apcups power supply is to ensure the continuous operation of electrical equipment in case of grid voltage drop or interruption. At present, apcups, as a backup power supply, has been widely used in hospitals, banks and data management, and plays an irreplaceable role in power grid voltage interruption.

1. When the power supply is normal, the rectifier and inverter work, and supply power to the load and battery floating charge at the same time. When the power supply is interrupted, the rectifier stops working, and the battery supplies power to the load through the inverter, so as to realize uninterrupted power supply. If the battery fails or the battery energy storage is exhausted, the UPS power supply will be changed to the bypass power supply.

2. The delay power supply time of Schneider UPS power supply depends on the capacity and load of the battery. The battery with standard configuration can only be used for emergency handling of business for about 5 minutes after power interruption. Businesses that need a long time delay will calculate and determine according to the specific time of the delay; for example, 2 hours and 4 hours, and determine how much time the delay is when the battery is fully loaded; for example, 2 hours can be powered when the battery is fully loaded, and 4 hours can be powered when the battery is half loaded.

3. Generally, how long the UPS power supply for the load is mainly determined by the load power of the load equipment to the UPS power supply, the total battery capacity of the UPS power supply and other factors. If the longer the power supplied by the UPS is needed, the number of batteries in the ups should be increased accordingly.
