Smart-UPS X 3000: Power Factor Correction Fault after losing input power

This was originally posted on APC forums on 3/2/2021

After losing input power to this UPS, it now won't power on correctly again. The warning led becomes red, all others are off.


We have a management card attached and can access it. We see the warning message A power factor correction fault exists.


This prevents me from turning output power on or running a self test.


When I try to turn the UPS off and on again, it comes back to the same state, and the logs say:

Smart-UPS X 3000
 2 Critical Alarms Present
  • The output power is turned off.
  • A power factor correction fault exists.
 3 Warning Alarms Present
  • The power for switched outlet group 1, Outlet Group 1, is off.
  • The power for switched outlet group 2, Outlet Group 2, is off.
  • The power for switched outlet group 3, Outlet Group 3, is off.

Current input voltage seems to be normal: Input Voltage: 226.5  VAC @  50.0  Hz
