Disable/change AVR on SUA1500i

[Anonymous user]

Hello

I have SUA1500i

In my house i have lots of electric heaters and input voltage drops often under 200VAC. AVR kicks in to compensate for low input voltage.

It happens very frequently (4 ou 5 times a minute on winter) and UPS click very often.

When it AVR activates output voltage goes as high 240-247VAC for a few seconds.

My active PSU don't need AVR and i would like to disable it or lower it. Computer works very well without UPS and i only want power loss protection.

I tried low AVR to 196 but AVR still kicks. 186 or disabled would be fine for me

thanks for helping.

An APC Smart-UPS RT 1000VA would be better in my case ?
