The UPS (Uninterruptible Power Supply) switches to bypass mode under the following conditions:

The UPS (Uninterruptible Power Supply) switches to bypass mode under the following conditions:

1. Main power failure: When there is an interruption or abnormal voltage (either too high or too low) in the main power supply, the UPS automatically switches to bypass mode to maintain the continuity of power supply.

2. UPS failure: If the UPS itself malfunctions, fails to operate properly, or cannot provide a stable output power, it will automatically switch to bypass mode.

3. Overload protection: When the connected devices exceed the UPS's rated load capacity, the UPS may trigger overload protection and switch to bypass mode to avoid further damage.

4. Battery failure: If there is an issue with the UPS battery, such as low battery level or damage, the UPS may switch to bypass mode to ensure the stability of power supply.

5. UPS maintenance: During UPS maintenance, troubleshooting, or critical component replacement, it may be necessary to switch the UPS to bypass mode to ensure safe operation and continuous power supply.

These are some common scenarios that may cause the UPS to switch to bypass mode. When in bypass mode, the UPS no longer stabilizes or filters the output power but directly passes the main power or bypass power to the connected devices. Please note that the specific UPS operations and switching logic may vary depending on the manufacturer and model. It is advisable to consult the UPS user manual or contact the manufacturer for accurate information.
