Hi!</x-html>From ??? at ??? Thu Sep 10 22:43:08 1998Mum and I just talked about Ups last week after a thunder. She is taking care of the computers at a company here.
She told me that the Ups could only survive a short time without power, about a couple of hours.
They are mainly used to prevent what we in Sweden calls "spikar" and if you translate it right away it would be something like "nail" as "hit the nail on the head".
You probably will call it something else.
I don't know exactly how these "nails" works, so I'm not trying to explain it. :-)regards,

Hi Chen,
When I was into reef tanks a couple of years ago, An aquatic version
of an UPC was just coming on the market. It was designed to run the
main pump (or an auxiliary one that draws less). The UPC could run a
modestly sized pump for a surprisingly long time. It has been a while,
but I recall that they could go for most of a day (I honestly don't
remember though). Of course with a reef tank, water movement is a mater
of life and death and even just a few hours could make a difference.
For most FW tanks, I suppose it could be put on a timer to cut the pump
on and off to extend the total running time. But if you loose power for
days at a time, a generator is about the only thing I can think of.
