Hi Folks,
Just wanted to pass on Ken Murrays email at USTech.
He has a wealth of detailed knowledge about these and has been extremely
helpful in providing guidance for purchase and also in finding the best price.
We usually buy Eatons from him and have had great success.

Hi All,
Thank you for this discussion as we are also looking for new UPS(s) for our
NMR and a new LC-MS. We had two UPS's for our two Bruker 500 MHz systems.
The newer one was a Staco UPS and never worked even after replacing the batteries.
It failed every single time there was a power outage. It also failed any time
we tried to do temperature experiments when the BCU kicked on. The older one
(approximately 30-40 years old) has never failed and lasts for at least 30 minutes.
That one was from Best Power, which sadly, doesn't appear to be in business any
longer.
As for the newer UPS that failed, my feeling is that it did not meet the kVA
requirements of the spectrometer (AVANCE II) but I really don't know and it
was purchased before I started working here. If someone could comment on
the kVA requirements for a Bruker 500 MHz w/ NEO console, I would appreciate
it.
The other variable is how long the UPS stays on after an outage. I live close
to work, so if the UPS stays on for >20-30 minutes I can rush in and do a
proper shutdown if there is an outage. So that's another consideration.
Thanks for your feedback.
Mark

Hi –
We are looking into installing an uninterrupted power supply for our labs
(three Bruker spectrometers). I’ve got a recommendation from Bruker,
but I wanted to offer management several options before we pick one.
What UPSes do you guys recommend? Are there any that people have found work
particularly well?
Thank you!
