| Almost all businesses now operate
some form of computer system. Consider the effect of a sudden
loss of supply and the immediate shutdown of the computer system.
· Read some of the Frequently
Asked Questions
Incurred costs could be:
· Loss of business while the computers
are off.
· Retrieval of lost business when power returns.
· Retrieval of lost or corrupt data.
· Damage to computer components.
· The stigma of your company's vulnerability.
It is usually the situation that the combined cost of all these
problems will cost much more than the expense of installing
a suitable UPS unit.
Questions often asked:
Why should I worry about power problems?
Even small disturbances in the main electricity
supply can cause damage to electronic equipment. Power problems
can cause unplanned shutdowns and data loss. All these problems
can cost your company a considerable amount of money.
How common are power problems?
A recent Power Quality Study revealed that the
average computer system is subjected to 289 potentially damaging
power disturbances per year.
How can power problems be avoided?
All essential electronic equipment should be connected
to a voltage regulator, power conditioner or, best of all, a
UPS. A UPS will maintain a steady supply of power irrespective
of the mains supply quality.
We already have a generator…
Generators can not start instantaneously. It tales
less than 1 second without power for a computer system to fail.
A UPS unit is a "no - break" power supply, giving
continuous power irrespective of the disturbances at the input.
A good quality UPS unit has three main
functions:
1) Electrical Filter - Through its design and
operation it will block out any disturbances in the mains supply
and give a clean sine wave output. Click the blue box in the
diagram below to see how unregulated voltage is affected by
a UPS.
All computer equipment is susceptible to mains
supply disturbances. Most vulnerable are the hard disk (data
corruption) and microprocessor (malfunction).
2) Voltage Regulation - The standard voltage in
the US is ??? or ??? Volts. What is actually supplied may be
much higher or lower than this and may prevent systems from
operating correctly.
A UPS unit will give a steady output voltage irrespective
of incoming value. Again, click the blue box to see how unregulated
incoming voltage is affected by a UPS system.
3) Battery Back Up - Whether the mains supply
dips, sags or disappears completely the UPS will use its battery
power whenever necessary to give a steady output. Again, click
the blue box to see the response of the UPS to an interruption
to the power supply.
