Hi all,
Not sure if this is the right section to post this in, but just wanted to know what Uninteruptable Power Supplies you use for your HPLCs/GCs?
Keep getting black outs and need one. Been looking at this one:
CyberPower CP1500PFCLCD PFC Sinewave UPS 1500VA 900W PFC Compatible Mini-Tower because it outputs a sinewave, but it is a little pricey, seeing as I need 3 of them.

Hi Duarte
The last time I looked at this it was more cost effective to get one big unit for multiple instruments rather than a small unit for each instrument.
I have heard that Agilents are very fussy about their power, probably Agilent can advise on UPS output specs.
The other major variable is how long the power cuts last, because this determines whether you can run the UPS form capacitors or batteries. Batteries are a recurrent cost.

Yes I have just gotten off the phone with Agilent and they essentially echoed your advice!
Thanks

We use Falcon SG-6 units on our GC-MS systems, expensive but rugged and tech support is good. My unit is 13 years old, I can still get parts for it the engineers still answer my emails and phone calls without asking what 'service plan' I'm on
.
I would not be surprised if it lasts another 13 years in which case I will retire before it does

The oven heater in the 6890 causes problems with some UPS's, I think because they use phase-fired controllers
https://en.wikipedia.org/wiki/Phase-fired_controllers so we had to go with fully regenerative units.
