An UPS or an uninterruptible
power supply is actually a device which lets a computer to continue to run for a
short period of time at least, after the primary source of power is cut off. It
also gives protection from sudden power cuts. A UPS consists of a battery which
starts working when the electronic gadget detects a cut down of power from a
primary source. In case a person is using his computer while the UPS is
notifying him the power failure, he will have the time to quickly save any
important data that he was working on and then exit carefully before the
secondary source of power (that is the battery) runs out. After all the power has
run out, every piece of data in the computer's RAM (random access memory) will
be erased. When such power failures occur, the UPS will stop the power cut in
order to prevent any kind of damage that the computer is likely to face.
The ups systems
are basically of two types:
1.
SPS (Standby power systems): Such a
device is known for its ability to check the power line and then switch
immediately to the battery power when it senses a trouble.
2.
On-line UPS devices: These systems
provide the protection of highest level against every type of power problem and
provide instantaneous power backup.
The main
function of a UPS system is to offer power for a short time, after the main power
source has failed. However; most of these systems also have the ability to
correct certain common problems related to utility power such as:
·
Sustained overvoltage or voltage
spike
·
Temporary or continual decrease
in the input voltage
·
Noise that is described as a
transient or oscillation of very high frequency, usually inserted into the line
by some nearby equipment
·
Unstable behaviour of mains
frequency
·
Harmonic distortion: This is described as
a removal from the actual sinusoidal wave form that is expected on the line.
UPS units are usually
divided into different categories on the
basis of their working mechanism and the environment they are required to work
in. Often manufacturers also distinguish the
products according to the total number of power failure cases that they face.
The UPS devices are
available in a number of different sizes and forms. However; two of the most used
forms are the tower model and the rack-mount model.
If you are residing anywhere in Delhi and your
area is prone to power failures every other day, don’t worry. Instead of buying
an ups device, you can now easily get them from any UPS rental company in Delhi. It is better not to trust just any
company that you hear of in advertisements but instead go for the few well
known, old, UPS Rental Services &
Solution Company.
