Dear colleagues,
Several people ask me to post a summary of the many responses I
received. Since there are so many responses, I took the lazy way to just
copy and paste them below. I hope it is ok to leave the senders' names
there. I think I have everyone's response, but it is always possible
that some of the responses may go not go through the filtering system. I
apologize if that happened.
I just realize in my last email that I meant that I could NOT write back
and thank each of you who responded to my request for UPS, but I
accidently left the "NOT" out. I apologize for that.
Best regards,
Wei Li

Hello,
We have been using a Liebert UPStation GXT for many years now and are
happy with their performance. We use 3- for a Bruker MicrOTOF-Q LC-MS,
Bruker DRX400 NMR and Bruker AC200 NMR spectrometers.
I hope this helps!
Cheers!
Paul
Wei,
We have been using the UPS described in the attachment since our VNMR
500 Hz was installed late in 2005. We have yet to have the instrument
go down due to power failure.

Hi Wei,
We just bought the following UPS backup system for our INOVA 500 MHz
console.
Eaton 9135 UPS Tower, Online UPS 5000VA 208V, it has ~ 8 minutes back-up
run time, cost ~ $3,800
Hope it helps.

Hi Wei Li,
Here at Merck, we have all of our systems on APC Symmetra Power Array
models.
The units are setup to Ethernet me when a system fault or failure
occurs.
We swap out the batteries every 4-5 years.
The power modules & intelligence modules are plug & play and easy to
replace so maintaining them is quite simple.
Best regards,
Tom
Liebert 6.2 kVA works well. You can buy from CDW for a decent price.
Make sure you get appropriate plugin attachments for connectors in and
out. You will need 220vac 30 amp for power source.
Dear Dr. Wei Li
As the frequent power interruption is also a common phenomenon in India,
we always recommend customers to buy UPS.
My suggestions are below:
- If you are buying a liquids only configuration then a 7.0kVa with a
battery backup duration of 30 minutes on full load will be adequate
- If you are now buying a liquids only configuration followed by a
future addition of other modules such as Auto Sampler, Solids Module,
etc., then a 10.0kVa with a battery backup duration of 30 minute on full
load will be adequate
- The UPS must have a Single Phase Output (In India, the power supply
from grid is Three Phase. So, the UPS systems manufactured and sold in
India accept Three Phase Input and Single Phase Output)
Exact power consumption and corresponding details are clearly outlined
in our Installation & Planning Guide. Needless to add, further and
detailed information can always be obtained from our Field Service
Personnel.

Hari
Dear Wei,
We have the following UPS fitted for our Bruker 400 NMR (for supporting
console and associated accessories that draw power from the console).
2kVA/1.4kW Model ZP2K

Ann.
Hi Wei,
Before selecting a UPS model, you must first select the NMR system in
order to know how much current it draws. You must also decide how long
of an outage you want the spectrometer to survive. Once the total
current and duration are determined, then you can choose a UPS. The NMR
manufacturer you buy from can also help you choose a UPS. You might
even put the UPS into the NMR bid so the NMR manufacturer will supply it
alo0ng with the NMR.
Cheers,
Jerry Hirschinger
Hello Wei,
We went through the same exercise but for two spectrometers. We found
that the cheapest solution was to buy one UPS on the regular voltage
108V (three phase) and put it before the transformer which boosts up the
voltage to the higher values. - Just something to think about.
Cheers
Ulli
=================================
Hello Wei, I got it from GE. It was the cheapest one and so far so good.
We bought it around three years ago.
Regards.
Carlos.
Dear Wei Li,
If you get a Varian 400MR, the voltage is 120V and a 2KVA UPS is
perfectly fine for intermittent power outages. You will need larger
battery backup if you encounter longer duration outages. I just grabbed
one of the UPS units we use for general chemistry instrumentation (sorry
I don't remember the make just now). I have a smaller UPS for the data
station and the printer is on house electricity (don't put laser
printers on UPS, they draw lots of power all at once and they cycle
alot).
Of critical note for you is whether your house air supplying the NMR is
on an UPS. If not, be sure that the vendor assures you that the system
can go without air and not put you in a precarious situation
(autosampler without eject air causing stacking of samples in magnet,
etc.).
good luck,
Pat
I just did this for a Bruker 400.
Eaton Powerware 9135
6000 VA
4200 watts
208 V
Includes PPDM
$3,340
Don't put the PC on it.
Console only.
We got the Liebert UPS ($6,000) for our Bruker 400 with SampleJet. We
didn't buy the extra battery cabinet ($1,000). At the load we have on
it I think we could go about 45 minutes without power. We've had a few
short outages and everything ran smoothly. I know that APC has cheaper
ones but they don't operate the same way. The Liebert actually converts
all the AC to DC and then back to AC, so you have a lot more protection
from spikes and slumps. We thought it was worth the extra money (see
attached quote).
Neil
Hi,
We used Liebert 6KVA UPS that Bruker recommended. So far so good!
Weiguo
Wei,
We use a 12 KVA Eaton Powerware BladeUPS. This is modular and
expandable to 60 KVA, so it's likely too big for one system. We got it
because we wanted to put all of our future spectrometers and peripherals
on it. Eaton sells a wide variety of UPS systems for small and large
needs, and I found them to be of very good quality for the cost. They
also work extremely well, so we sail through all power outages and
flickers with no problems. We can also have it warn us of a power
outage and bring down the spectrometer and host computer if necessary.
Ours can also expand to use several battery modules to give us
protection for several hours as well.
Regards,
Patrick
Hi Wei,
We have a new Varian 400MR, which is 110V and it is nicely backed up on
a simple APC smartups-2200 unit, which I think I paid ~$800 each for,
maybe less. My original plan was to use two of these units- one for the
computer and one for the console, but it drew so little that I used one
of the UPS units elsewhere!
So, off of one 2200VA unit I am running the console, the pneumatics
unit, a 7600 sample changer, protune module and the Dell computer. Back
up time appears to be > 1hr.
I forget whether the new Brukers are 110V now too.
Hope that helps!
Neal
======================================
READ THE SPECS I'll just keep saying that over and over. STUDY THE
INSTALLATION MANUAL. I do a lot of this.
Are your outages brief, transient? If the compressed air system goes
off you are out of business in any case.
You should check in the installation manual for the voltage. We are
getting a new 400 from Varian which runs on 110VAC, a welcome surprise.
This is the starting point. Then you need to know the load, also in the
manual. Now you can begin to search for an UPS.
But what about your compressed air. We have a very fancy, medical
grade compressor for multiple instruments because the air needs to be
dry, especially if you are using an FTS as part of your VT system. In
the location of our new instrument, a new building, the house air has a
-40C dewpoint and we don't need a dryer. Even if you are not doing VT
the air must be decently dry or you will get condensation in the lines
and the probe.
And the list goes on. Do read current documentation for the
instruments under consideration.
Best of luck,
Sara
================================================
We use a couple of different ones:
On our Bruker 400:
Tripp-Lite SMARTUPS
SU3000RTXL3UHV
I think you have to specify 208V, single phase for the output
This lasts about 30 minutes or so.
On our Bruker 500 we have
Tripp-Lite SMARTUPS
SU5000RT3UPM
with an additional battery
BP240V5RT2U
This instrument has a few more modules on it that draw more power and
the extra battery extends the time. Under normal operation, this should
last longer, maybe an hour.
For a proper rating, call the UPS manufacturer and let them know what
the maximum current draw you have and how long you want it to last in a
power outage.
Keep in mind that the batteries for UPSs only have a life expectancy of
about 4 years depending on the load and how often they get cycled, and
they are a significant fraction of the cost of a UPS.
Also, UPS batteries really do not like to be fully drained for very
long.
The UPS will shut down before they get fully drained, but you want to
have it charging back up within a couple of days. We had a lab move at
another facility and they left them in a crate for two months. The
batteries could not be recharged and they had to buy new ones.

Hi Wei,
We have a Liebert GXT2 208V system on our Bruker Avance II 400MHz system
and have had no problems from it. It's about $6K up front, but saves
wear and tear on the system from power fluctuations and outages. A bad
power spike could fry several boards at $2K to $5K each and the cost of
the UPS is only about 1.5% of the system cost.
Cheers,
Rick
Hi Wei,
I've had pretty good luck in two different facilities with Powerware
9125 UPSes. Eaton (powerquality.eaton.com) had purchased Powerware at
one point and is the supplier. Unfortunately, that UPS has been
discontinued. Their suggested replacement is the Eaton 9130 which I will
assume is a good product but have no experience with. Their reps were
pretty good at getting me what I wanted/needed.
The last time I bought one (2006), a 6 kVA 230V unit was quoted at about
$2300. That will keep a 4 channel Inova 500 or 600 running for at least
20 minutes running triple res protein experiments. I think they only
sell the higher rated units in hardwired models, but you (or an
electrician) can always put plugs/receptacles on the non-UPS ends of the
cords you need to attach - and probably need to at the spectrometer end
anyway.
As for maintenance costs, we replaced the batteries in an identical unit
here last summer which was at least 4-5 years old - in hindsight, I'm
not sure the old ones really needed replacing, but it was acting strange
and there's really nothing else to change if the breaker is good. There
are two battery packs that cost ~$435 each ($325 each with
academic/government discount) plus shipping. They would charge nearly
$600 labor to install them on site for you, but in all honesty it's a
few screws, <10 minutes, and dead easy as long as you can read
directions and lift 70 lbs a short distance.
Our pumped 800 magnet here has a GE unit (supplied by Bruker) on it that
also seems to work well. It did die after 4-5 years but was easy enough
to replace.
Hope this info helps,
Andrew
========================================================
We bought our UPS directly from Bruker for our Avance III 400 MHz
instrument. Our purchasing department initially did not want to buy it
from them because they thought they could get a better price. During
the time they were looking, the voltage fluctuations were causing fuses
to blow. Well we ended up getting the UPS from Bruker and have not had
one problem.
Since the computer, printer, and lamp all go thru the UPS too, I can
still analyzed samples when we do not have power.

Wei:
I have used a PowerWare 9170 (now Eaton power) 18 kVa for my
solids and soln INOVAs with no problems since 2000 (except the need to
change batteries, which you have to do for any system).
Regards,
WLJ
We have an APC smart ups model 3000. There are no issues unless there
is an extended power outage (we went out for 6 hours this summer). In
that case I would suggest a back up plan, whether that be an emergency
generator, or a simple phone call to someone who can shut the console
down in an approved manner.
Heather Starke, Ph.D.
Hello Wei,
I have a UPS on each of three systems, two 400MHz (both with BACS sample
changers), one 500MHz (with a CASE sample changer) and there is about
20-25 minutes of battery time with this load. They are 6kVA Liebert GXT
UPStation's with Maintenance Bypass modules and they have worked
perfectly for upwards of 8-9 years now. The only maintenance I have had
to do was to exchange to 20 onboard batteries, once for each of the
three UPS's after 6-7 years (the UPS will beep to let you know it's time
to replace the batteries. And yes, the UPS's take 208V as input.
The UPS's have allowed me to leave the SGIs controlling the
spectrometers running for years without rebooting... Current record is
719 days (and still counting) of uptime! I am pretty darn proud of
those numbers.

We have an American Power Conversion UPS system on our Bruker 400 MHz
ULH SS Avance II+. It supplies 208 V for approximately 30 minutes. It
also filters any irregular voltage coming through. Bruker provided it
to us with the system. We have frequent power outages as well. It has
been quite helpful.
Hi Wei,
We just had a new Avance III console installed 2 weeks ago and it came
with a Liebert GXT2-6000RT208 at a ticket price of $6K from Bruker.
Good luck.
Russ
Wei Li,
We have two UPS here, both Leibert GXT models. They have run well for
many years, but we don't haven't many problems with power outages.
Good luck.
