Hi all,

We are unfortunately facing many unplanned (random) electricity outages/voltage variations in our Institute (it's a very old building) and our systems (and particularly lasers) don't like it too much... I was wondering if some of you are using UPS units to protect your confocal/2-P systems? If so what type of UPS are you using? All the info you could provide would be most welcome, thanks in advance.

Hi Mario,
We use APC Back UPS Pro sinewave units for a lot of sensitive equipment including CCD and CMOS cameras, test equipment, and other science-related instruments.
They have an excellent track record and reliability.
Eg BR1500VA and other models.

Good luck.

When we designed our new lab, we investigated which equipment is subject to damage.
Our multiphoton laser (Coherent chameleon Ultra II) has a built in safeguard with an internal battery sufficient to cool down the laser. The software reports the state of the battery. This is not written in the laser specs so it is worth asking the company if they have such a system or not.
Argon lasers will get their lifetime reduced if repeatedly turned off without cooling but there is no impact if it happens seldom. This is a problem if it happens often as seems to be the case in your institute.
The rest of the equipment (cameras, computers...) can be turned off suddenly without damage.

However the main problem is the spike that occurs when one turns the power back on. This is very damaging for a lot of equipment including the computers. It is very important to have a good spike protection system. Alternatively unplug all equipment before the current returns or setting the fuse back on and painfully replug them a few at a time.

Med vänlig hälsning / Best regards

We have 2 units of 3000 VA (https://www.riello-ups.es/products/1-sai/44-sentinel-pro) for all components of our Leica SP2 AOBS, and only one unit for Nikon A1R+ to ptotect Argon laser and PC (in order to can save the current data).
All conventional microscope PC's have installed WinOFF programme to switch them off if 30' nobody is using them.
Safely regards,
Konstantin

We use the following UPS setup to backup our 2-P workstations:
UPS:
https://www.cyberpowersystems.com/product/ups/smart-app-sinewave/pr2200lcdrtxl2u/

Battery extension:
https://www.cyberpowersystems.com/product/ups/extended-battery-modules/bp48v75art2u/

With this setup we can run the workstation for about 15 minutes with the
laser on (about 4 minutes without the battery extension), to give
enough time to safely save an experiment and shut everything down.  Once
the laser is on standby, the UPS can run everything else for hours.  As
others have said, the two major considerations are that you have enough VA
(2500 per high current laser system should be sufficient), and that the
output is a true sine wave, not an approximated one (approximated sine
waves can put unnecessary stress on power supplies for sensitive
equipment).

Hi Mario,

We have a UPS for every system in our facility. They are primarily 3kVA systems, with a couple higher spec, e.g. the one for 3 phase (20kVA – over spec but was the only one available at the time).. They are mainly Socomec but we also have MGE. They are all online UPS so smooth as well as protect from spikes/outages.

Every microscope user is trained to listen for the beeping and shut the system down if this is ongoing. Also, we have them all plugged into essential power sockets. These sockets are provided with power by generators in the event of a complete campus power failure but don’t come on if it’s just local, e.g. one building/floor.

We started adding these to every new system after having had a very expensive repair bill ($10k) after our Leica confocal went off and on again. They are included in our business cases as a necessary expense.

The UPS are cheaper than the necessary repairs. We also have a contract with a local supplier to check them and replace batteries regularly,. Otherwise, they wouldn’t be much use.

They are also really good for the time-lapse systems because a short outage or spike would otherwise terminate the experiment immediately.

Kind regards,

Jacqui

Hi Mario,

One more thing I forgot to say is that our 20kVA system has an additional use as an alert system. If the power goes off, it is set up to send a signal to a phone relay system which calls our contractors and alerts them to the power outage. We have 4 phone numbers so it calls people in order and if the first 3 don’t answer, I get the call and can alert the necessary staff.

Kind regards,

Jacqui

As a related aside, most UPS systems use lead-acid batteries for storage.
These typically have a lifespan of 4-5 years in a typical UPS. Make sure to
replace them after about four years in service. Better quality UPS systems
will include an alert to indicate when the batteries are aging out.
Batteries also don't fare well in storage, so it is pointless to buy spares
ahead of time. Make sure you have some lead to account for ordering and
delivery time of the new batteries, and keep tabs on your vendor over time
to ensure you can still get the model of battery you need.

When I ran a core facility I always has my equipment on UPS systems of
different types to protect the electrical equipment in an outage.

Hi Mario,
I prefer "online" (or double conversion) style UPS.
One 2P system I used to work with was backed up by a massive 6 kW GE
Digital Energy UPS (maybe an overkill, but there was an Ar-ion laser as
part of the system). Some smaller GE Digital Energy units (1 - 2 kW) were
also sold as Franek. Very robust, but rather old.
We also use GE VH-series units on some smaller equipment, like plate
readers and liquid chromatography systems. I now only have one microscope
backed up, it's a spinning disk confocal (no Ar-ion laser), and the UPS is
APC SURTA2200 (it's the "RT" series, that means "online"). I got it for
$200 and I'm happy with it.
Of note is that the microscope is connected to emergency power, and there
are more outages on emergency power than on regular outlets (once or twice
a year to test the generator and switches, cca 15 second outage to crank up
the diesel engine). So for any computerized equipment connected to the
emergency power a UPS is a must!
Best, zdenek

Hi everyone

Nice discussion. So if I summarize what is needed:
- good UPS with batteries regularly checked and replaced when needed
- back up power from a diesel generator that takes a short while to take over (basically it is not enough to have the back up power without UPS)
- someone on call who can come before the generator has had enough

This is exactly the conclusion we came to when designing our new building.
But all this is necessary only if there are power cuts several times per year.
If the power cuts come seldom and there is a good surge protection system, there is no need for these expenses. This is of course to be balanced with the cost (and number) of the wasted experiments.

Since we have less than one power cut per year, we have skipped UPS, backup power and on call person and focussed on the surge system.

Med vänlig hälsning / Best regards

Sylvie
