Technical FAQs 4

What is an uninterruptible power supply (UPS) system?

Uninterruptible Power Supply (UPS) systems are essential for ensuring that critical devices remain powered during power outages. However, like any other technology, UPS systems can experience issues that may affect their performance and reliability.

Why does my ups not start if the battery voltage is low?

The low battery voltage indicator on the UPS panel will stay on and the buzzer will sound. Based on the this UPS failure phenomenon, it can be judged that the UPS failure is caused by the battery voltage being too low, resulting in the UPS failing to start.

What happens if a UPS battery is too low?

I am also getting a lot of alarms that say: "UPS: The battery power is too low to support the load; if power fails, the UPS will be shut down immediately." followed by "UPS: A low battery condition no longer exists", and if utility power fails Unit shutdown immediately. UPS configured Low Battery Duration is 2 Minutes.

Why does my ups turn off all outputs without mains power?

If the mains detection circuit is not working properly and the UPS does not have the function of starting without mains power, the UPS will turn off all outputs and displays. If the city detection circuit works normally, then check whether the battery voltage detection circuit is normal.
