Re: Efficiency of Sola Constant Voltage Transformer?

I'd be a little cautious about this. The nature of the load the xformer
is driving will effect how the xformer performs. I'd ask APC (and/or
check their FAQs) whether CVS might be a problem. I had a fluorescent
desk light that would not start when connected to a CVS - not the same thing as a UPS but ....

Google found me this link sola-heavy-duty.com which is a spam-infested mess
and NOT Sola's site. Thanks for the correct link.




but I'm considering adding a model 23-23-220-8 CVS ahead of our UPS to 

clean

up the harmonics from our generator so that we can run the UPS on the 

'high

sensitivity' mode without having it constantly switch to battery. 

I wouldn't.

I'd be more worried about the output waveform esp. during any power outage
situation. I'd certainly run the idea past the UPS maker first. I suggest
you get APC to re-engineer a solution for you.

Too costly. I bought the UPS as a refurbished unit. I'm shopping for a used
CVS on Ebay. I have hundreds of dollars to spend on this, not $30,000+ for a
reengineered solution.

My testing has verified that our problem is not generator frequency, but
harmonics. The UPS sensitivity can be lowered, but then when it switched,
several computers on the network reboot. Only in the High sensitivity
position does the APC UPS switch fast enough to avoid rebooting computers on
the network. Although on the setting below High sensitivity, the UPS is
happy on generator power. Only problem is we have stuff rebooting when it
cuts over.
Hence, we must run in the high sensitivity mode of the UPS and clean up the
input power with the Sola CVS.
