Re: Backup power supplies

Hi Ed.

This is really a simple task...

In my company (coincidentally a power company) we have a UPS sized
large enough to run every piece of equipment that needs uninterrupted
power...the AS/400, some PCs and our phone system.  We have a
generator with an automatic transfer switch so when the power goes off
the UPS keeps the required systems hot.  Then the generator kicks on
and after it comes up to speed the load transfers to the generator.
We're using a Best Ferrups for the job -- it's a constant-on type UPS
(It converts outside AC to DC, then back to AC on a full-time basis)
so the the equipment doesn't even know the transfer happens.  The UPS
will eat 57-63 Hz power (which the generator can easily provide) and
then converts it to clean 60Hz.  Best Power is at
http://www.bestpower.com

The generator and transfer switch is made by Onan.  If you go to their
website (http://www.onan.com) you can find a local dealer who will be
more than happy to help you size the transfer switch and generator to
appropriate capacities.
