There’s a big difference between a power conditioner and a power regulator, some conditioners may filter out some high frequency noise on the power or disconnect the power if it goes over a certain high limit voltage setting, they do give you a handy place to plug equipment into! A regulator will keep the output voltage the same or within a few volts as the input voltage raises or drops within it’s operating range, my Furman regulator is something like 95 to 140.
Look at getting a battery back up / “UPS” that is always running on the inverter, that will give you regulated voltage output at all times and there is no switching time from when you loose power to battery power coming on, even though that happens really fast there can be a slight glitch during the switch over.
One time I did have the front panel screen freeze on my QU Pac. Not sure at what point during the day it happened, it was running all day at a festival on a voltage regulator
from a soild power source. The iPad control was working fine, never figured it out and it’s never done it again.
