UPS can maintain the time to connect devices without mains power, providing additional time for data storage and orderly shutdown of programs.
No, online UPS (uninterruptible power supply) cannot function without a battery. The battery is a key component of an online UPS system, and its main function is to provide continuous and stable power supply to connected devices in the event of a power outage or interruption.
The following is the typical operation mode of online UPS:
Double conversion process
The online UPS system adopts a dual conversion process. The AC power supply from the mains is first converted into a DC power supply by a rectifier inside the UPS. Then use the DC power supply to charge the UPS battery.
Continuous battery operation
At the same time, the inverter in the UPS converts the DC power generated by the battery back into AC power, which is then supplied to the connected devices. This continuous process ensures that the device receives a stable and stable power supply, without any interference from mains power.
Backup battery during power outage
When there is a power outage or abnormal power supply, the online UPS seamlessly switches to battery power without any conversion time. The uninterrupted power supply of batteries ensures that connected devices remain in operation until normal mains power is restored or a predetermined threshold is reached.
Power fluctuation protection
Batteries also play a crucial role in isolating connected devices from power fluctuations such as surges, voltage dips, spikes, and electrical noise. It acts as a buffer, providing clean and stable power output to the device.
