Hi all,
Just a couple of things I'd like to add. First, I've had some dealings
with Vertiv/Liebert and I second whoever said that they've been great to work
with. In my experience they've been quite responsive and know what they're doing.
Second, it's hard to say how long the batteries would last because the current
draw of your console is going to depend on the configuration. I have a
report from a 2-channel NEO console that says it draws 3.8A or so at 208V.
So that would be 790 VA. Below is the table from a Liebert GXT5-6000VA unit
with expected battery times vs load for various numbers of external battery packs.
So I'd expect one of these to last between 30 minutes and an hour.
One other note--with the NEO consoles if you can connect remotely you can shut the
console down remotely, so if you get an alert that the power has gone out and you
can connect remotely, you can just log in to the system and turn it off from home.
Cheers,Mike

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!
