Nut upsuser - Sep 2006 - (Fwd) Re: Slightly OT: Generators & UPS

Hi,

I'm the original poster on the subject.

Thanks for all the replies.

A few  more points.

The generator outputs 7kw @ 220V.

The total PC's supplied is about 9.
I estimate power consumption to be
9 x 300w=2700w

4 halogens @ 400w each=1600w
10 Compact Flourescents @ 11w =110w

Therefore total power=4410w

Which leaves me with spare capacity of about 2590w (in theory).

I think its the halogen lamps that is helping "smooth" out the
power.
Previously, when I ran the generator, I did not have the halogen 
lamps
on, 
and the UPS failed to recharge.

Regards

Neither fluros or PC power supplies have a terribly good power factor.

Given they're over a quarter of your total load it's not surprising to
find
the generator change characteristic.

I'd look at adjusting the UPS settings if possible - you may be able to tell
it to be less sensitive to poor power.
