TALK ABOUT – BUYING THE RIGHT UPS
Power is unpredictable. A car crashing into a pole or a small flaw
in a transformer’s equipment can cause a blackout or, in some cases, a surge
strong enough to destroy most electronics in your home. Although rare, these
events can knock your computer offline when you need it most and cause
thousands of dollars of damage to other electronics.
The solution is not any mere surge protector but instead a UPS (Uninterruptible Power Supply). These
big, beefy units combine a high-quality surge protector with a battery that
will keep electronics running through a blackout (for a short time, at least).
Like a surge protector, a UPS only has so many outlets, and so
you’ll need to put a little bit of thought into how many devices you currently
have plugged in and how many are truly considered essential which need to be
powered by the UPS. Generally speaking, it’s a good idea to buy whatever you
need plus two, as that gives you some flexibility for the future.
DO YOU REALLY NEED A SURGE PROTECTOR?
Do You Really Need a Surge Protector? A surge protector is not the
same thing as a power strip! Here's how they're different and why you need
surge protectors instead, as well as how to choose a good one.
Many UPS units provide at least eight plugs, but also check how many
of them are actually powered by the battery. Inexpensive options often cut
costs by only providing battery backup to four or six outlets, leaving the
remainder unpowered. That’s won’t be a problem for everyone, but it can be a
nasty surprise if you learn about it the first time the power goes out.
Finally, if you’re using wired data connections, look for a UPS that
provides protection for them as well. This includes both old-fashioned modem
and newer Ethernet connections.
With your outlets handled, you’ll next have to ask yourself how much
power the devices connected to the UPS will consume. If the devices need more
power than the UPS can generate, they’ll go dead, even if the battery has
plenty of charge. Think of it like a computer’s power supply; if the wattage is
lower than what the computer needs, you’re out of luck.
You can find out how much power your PC (or other equipment) uses
with a wattmeter, which can be purchased online for about $15. Remember to
check the consumption of everything that you need to power. If you want to
power a desktop PC, for example, you need to add together the wattage of the computer
and the monitor.
Computer power consumption can be estimated. Most of the components
inside a PC have specific minimum and maximum power draw figures and, because
quality control is so tight, it’s rare of a part to break...
Now that you’ve handled the wattage, you should also think about how
long your devices need to run. Some buyers purchase a UPS because they want a
few minutes to shut down devices properly and save any work that was performed
on them. Others want a UPS so they can work through blackouts which may last as
long as an hour.
To figure out how long a UPS will power the devices you’ll connect,
add together the wattage they draw and then refer to the product’s runtime/load
graph. Usually, this can be found on the side of the package or, if you’re
buying online, in the description. The APC BR1000G Pro, for example, can power
400 watts of equipment for about nine minutes, or can power 100 watts of
equipment for an hour.
WHAT FEATURES DO YOU WANT?
You might think that the features of a UPS would be simple. You plug
in devices, and when the power it goes out, the battery kicks in. That’s all
there is to know, right?
Nope. Even basic consumer-level units offer features like
disconnecting battery notification, USB connectivity and a software suit that
can be controlled via PC to fine tune settings and see how much power is being
consumed. A beefier “professional” unit offers even more features, such as a
LED that reports remaining battery charge and runtime in minutes, and
hot-swappable batteries.
Most people won’t need such fancy extras, but simply knowing that
they exist is important. You’re paying for it, so why buy a UPS with fewer
features, if all other things are equal?
HOW GOOD IS THE WARRANTY?
A UPS promises to protect equipment worth thousands, perhaps tens of
thousands of dollars. When a product performs such an important function,
you’ll want some peace of mind. And legitimate manufacturers provide just that
through a connected equipment protection warranty.
Terms of the warranties can vary, but most will offer both a product
warranty (which covers defects in the UPS itself) and a “connected equipment”
warranty, which promises to reimburse the value of any devices destroyed by
failure of the UPS. The value of the connected equipment warranty can vary,
with most coming in between $75,000 and $300,000.
Of course, there’s the potential for gotchas, so you should probably
read the warranty online at the UPS manufacturer’s website before buying. For
example, UPS manufacturer APC offers data recovery as part of its warranty on
some products, an extra most competitors don’t provide.
