What are the voltage and current ranges of a UPS power supply?

How are the input and output power sources of a UPS specified?
An alarm has occurred on the UPS; what are the specifications for its input voltage and current? At what low input voltage will an alarm be triggered?
Typically, UPS units in instruments have an input of 220V and an output of 220V as well; since a UPS is an uninterruptible power supply, there seems to be no specific requirement regarding this. It depends on the devices you use electricity for. Input: 220V AC; Output: 220V AC
Reply to 2# 9shanghai: How long has it been in use? Check whether the battery is damaged.
The input is usually 220AV, and the output is also generally 220AV; there are also versions with 36V or 24V outputs. I’m not quite sure either of the alarm threshold for input below which it should trigger. Another under-voltage alarm below 200V.
Our UPS uses 220V AC as the input and also outputs 220V AC. If the input power is cut off, the UPS will definitely issue an alarm. What happens to the UPS if there are fluctuations in the input power?
Input parameters: Voltage: 220V AC±15%, 380V AC±15%; Frequency: 50±0.5Hz. Output parameters: Voltage: 220V AC±5%, 24V: adjustable between 24~28V, 48V: adjustable between 48V~52V; Frequency: 50±0.5Hz; Ripple voltage:
