Compensating for a high input voltage.

[FigJam]

Hello 

I am getting a "Compensating for a high input voltage" alert from a SMT2200RMI2U UPS.   I changed my power sensitivity to low to see if they would go away, but that did not change.  

Other settings are set to:- 

Rate Output Voltage: 230

Output Upper Limit: 253

Output Lower Limit: 207

Are there other settings that need tweaking on the UPS or should I call out an electrician? 

Hope someone can help. 

Many thanks.

Show me the data & event logs for the system.

If you have a True RMS meter measure the input voltage at the outlet and compare it to the LCD. 

You’ll probably find the input voltage is high. So no worries the AVR circuit is working exactly as needed to trim the output voltage.

So your equipment won’t be harmed! 👍

If you're still seeing the "Compensating for a high input voltage" alert after lowering power sensitivity, check if the incoming voltage regularly exceeds your output upper limit (253V). If the problem persists, you may need an electrician to inspect for fluctuations or high input voltage issues in your power supply.

Hi, Thank you for replying. Here are the logs

Appreciate the detailed log as it does show the voltage is quite high. But this assumption is based on what you shared as being the nominal input voltage of 230 VAC! 

If your location is indeed 230 vs 240 VAC the UPS is working exactly as intended and trimming the output voltage to protect your attached equipment. ☝️

If on the other hand your area uses 240 VAC. The system can be adjusted to 240 VAC and it will no longer go into AVR mode as the voltage is within the upper / lower transfer limits.

Ah okay, thanks for that. I am in the UK and I think it is 230 VAC
