Pls Help. Frequent UPS: Compensating for low input voltage events.

[ACVersus]

Hello,

My Smart-UPS 2200 is frequently getting UPS: Compensating for low input voltage events daily. The events seem to last 1 second. I don't know what is causing it. 

Current Firmware Version: ID1015UPS 04.1

I have attached the data and event logs.

Thanks!

Based on the logs you’ve provided the UPS is doing exactly what it was intended to do. Which is to provide clean uninterrupted power to your connected loads.

Both logs indicate your site is experiencing power quality issues or dirty power. 

You may consider adjusting the sensitivity and upper / lower transfer voltages. If you would like to reduce the amount of time and incidence of these events. 

Keep in mind decreasing the sensitivity allows a wider range of input voltage which may impact some network devices. Adjusting the upper & lower transfer voltage will also allow a wider range of input voltage.

Changes in either setting will reduce when the unit will go into battery only mode vs AVR mode.
