We see from your search that you're looking for information on the term "Uninterruptible Power Supplies",
and we have a large number of manufacturers' news releases and technical articles here on Engineeringtalk which will be of interest.
Let me be your guide.
Start with
the news release The true price of power supply harmonics from
Block UK, which we summarised at the time by saying "Bob Liddle explains how to reduce the effects of harmonic distortion on power supply lines, thereby eliminating equipment failures and cutting production downtime, repair and replacement
costs".
A few weeks before,
we featured the news release Lead-acid batteries cover all applications from
PowerPax UK: "A number of different series are available, low covering all applications with fast delivery and very competitive prices".
In October 2007, we covered the news from Eaton Corp
concerning its Essential-side MCCBs
- take a look at Switchboard provides uninterruptible power
which says: "Essential-side MCCBs open automatically in the event of loss of power but incorporate electronic time delays so that they re-close at 30s intervals to avoid stalling the generator".
Take a look also at the news release from Astrosyn International Technology, Chargers rapidly replenish lead batteries,
as well as Power supply offers full power conditioning from Powervar,
and IR sensors fit inside enclosures from QHi Group.
