Basic functions of UPS

1. When the grid voltage is normal, the mains voltage is supplied to the load through the UPS voltage regulation. The UPS with good performance is a good AC voltage regulator. At the same time, it also charges the battery in the machine to store the backup energy.
2. When the grid voltage is abnormal (undervoltage, overvoltage, power failure, interference, etc.), the inverter of the UPS converts the DC power of the battery pack into AC power to maintain the power supply to the load;
3. The UPS automatically converts between the grid power supply and the battery power supply to ensure uninterrupted power supply to the load. General computer equipment allows for small power interruptions (within 10ms switching time), but sophisticated computer equipment and communication equipment do not allow power to be interrupted (switching time 0ms), so you should confirm what UPS switching time you need.
