Alternatives to a UPS
you realize that you can do with out a UPS, you still should invest in a system to filter
the power line.
There are couple of devices that are usually bundled with a UPS, but can also be purchased
separately----a voltage stabilizer or a constant voltage transformer (CVT) and a surge
Poor man's UPS
The CVT ensures that (the output voltage that leaves the unit) stays within a
specified range and that it does not fluctuate. It also has a surge suppresser along with
a spike buster built-in. These devices usually maintain the voltage between three percent
of the required output even when the input voltage varies between 170 V to 270 V. You
would need such a device in areas where there are regular and high voltage fluctuations,
which really means most places in India.
buster is a simple filter that cuts or prevents spikes (See Glossary) from getting through
to the system. These are usually available in the form of extension boards and strips and
do not cost too much either.
thing that one could do to protect the computers to plug the system into a separate power
line-one that does not have any other heavy machinery like Acs or motors plugged on the
line. Also, kept all devices plugged to the same outlet or line, thus you will minimise
the chance of the devices having different voltages and one affecting the others because
of the difference.
motherboard in your computer system has a battery built-in so that the contents of the
BIOS (the settings made by the user) are not lost each time the unit is turned off. Using
the same concept, manufacturers are working towards implementing UPS technology into your
PC, so as to prevent accidental loss of data through a power breakdown.
Do you really need a UPS?
appear that there is little reason for an individual to invest in a UPS. In most cases, a
spike bluster and a voltage stabilizer may be just fine, as we discusses above .The worst
that could happen without a UPS is that you would lose a day's work and/or you would need
to reform your hard disk. Nothing more! Power surges, spikes other problems can creep in
through any of devices that are connected to your computer. This could happen through the
telephone line if you have a modem connected, or through a monitor that is not properly
earthed, or the external CD-ROM drive.
you are fully protected, you are really unprotected.
have been sound reasoning not to buy a UPS about five years ago, but not anymore. The
prices of UPS systems have been plummeting and you can now get an excellent UPS system for
your computer for less than Rs 8,000. It may be a good idea to take this chance and buy
peace of mind.
the term to describe the current that flows through the wires. Just like your washing
machine at home requires a water pipe of a certain thickness to be fitted, this describes
the amount of power that must flow through the wire. Like almost every household
appliance, computers are 5 amperes, though there are some devices that work on 15 amps
(which also has a large-sized plug).
Blackout: is what happens to you when someone hits you on the head. You are out cold.
And is typically what happens to the computer when suddenly there is no power supply at
Brownout: is what happens
when you do not blackout completely, but are just dazed. In computer and power parlance,
it means a slight dip in the power line, not a complete shut off.
something that you would like to drive into the linesman when your computer gets damaged
because of bad power lines. It actually describes the sharp peak that one sees on a graph
when power supply momentarily peaks far beyond its usual cycle.
Surge: is longer than a spike and
is like a gush or a wave of extra power running into the power line that is there one
minute and gone the next.
measure by which one can tell the difference between the amount of power that is available
in the power line. Of the two lines on the wall socket, one is kept at zero, while the
other carries a current. Touching these points could prove to be a shocking experience.
the power consumed or required by a system to work. Something like the number of calories
that will be burned during the normal operation of the appliance.
