I'll second the recommendation for the Toshiba 1600 UPS units.  I 
have two of them and they've carried us flawlessly through numerous 
small power outages.  Our Delta-V doesn't blink and keeps working 
while I spend the next 20 minutes bringing our non-UPS equipped 
Delta-S back to life.  In the future, every new instrument gets a 
UPS...

I bought the last one in early 2015 for around $6500.  I specified 
exactly what I wanted and our university purchasing department sent 
out a request for bids.

regards,

Charles
