If power is so flakey as to threaten robust protection already inside
electronics, then the UPS is also at risk. And will connect that same
flakey power direct to electronics. Then much later (after the bad
stuff is done) it will switch to battery (if not already damaged).

Essential to even protect that UPS is the properly earthed 'whole house'
protector. That actually does protect from anomalies so massive as to
overwhelm protection inside all appliances.

That UPS may be $100 per protected appliance. A superior and well
proven 'whole house' solution costs about $1 per. And is essential
because most anomalies that cause damage occur long after any homeowner
even considers disconnecting.

BTW, some of the 'dirtiest' power seen by an appliance comes from a UPS
in battery backup mode. Power so 'dirty' as to be potentially harmful
to motorized appliances. Due to robust protection already inside
electronics, that 'dirty' power is also ideal power.

If you do not already have one, then please learn how it must be
installed, why it works, and why is it the only solution found in even
facility that cannot have damage. A useful recommend will also provide
numbers necessary to obtain a minimally sufficient and superior
solution. This solution is even more essential in rural environment.




George Shirley didn't write that, Songbird did. Read my original post
and you will see that we have a whole house surge protector, that,
indeed, has protected us. My UPS system is only connected to the
computer and is only to allow me time to shut everything down properly
versus allowing a power surge or outage to do the job.
