The UPS

S ystem of A OOD I ninterrumpida, in English it means Uninterrumptible UPS Power Supply

A UPS is a device that protects equipment from surges or brownouts,
frequency variation, harmonic distortion, electrical noise and fluctuations
that can cause serious damage. Also allows you to work with normal
if power outage.

Basically there are 2 kinds of UPS (in fact within the ONLINE there are more variations but I will not talk about those types)

INLINE
are the most basic equipment and economic. They are aimed at protecting domestic
Pcs. The stabilizer works when a problem arises. While there are power
such sai
only makes small adjustments in the current and only work with the
battery circuit when the power goes out. ONLINE


Tension teams constantly uses UPS battery
or not there is power outage. The output current is regenerated
always continuous alternating pass and then again the DC-AC
(double conversion) obtaining a pure strain
optimal fully stabilized, in addition that the signal is a signal sent almost
square (instead of sine), which is working with computers really

There are 2 values \u200b\u200bthat represent the power of a UPS, the VA (voltiamperios) and
W ( watts).

When sai know what kind of choice must take into account the consumption of computer
(referring only to the tower) and peripherals can be connected
almost exclusively the monitor, as printers, scanners
or other components should not be connected to the UPS because
end up injuring the excess consumption that need this type of device on startup.
A tower with power supply 400W and a CRT monitor 17 "
300VA could be fed, but always add a little, so
would need to do a 400 or 500VA UPS (this will
could put even a 19" CRT rather longer), there is no encuenta the size TFT because the consumption of a monitor of this type is significantly less than any CRT monitor, if they were 2 ordebadores would require a minimum 600VA UPS and so on.
When a sai is for domestic use a UPS can be placed inline, but
for a company where it is always recommended a more
online and taking into account that in the industrial AC power is not
often be far from stable.

For a single computer with a 500VA UPS battery time can vary from 15 to 10 minutes when sn new batteries and may be declining while exhausted the life of the battery (usually a component we will have to change as time passes them to the car battery) if the same computer you will place a few 650VA UPS duration time would increase to a time between about 30 or 20 minutes, if sources 2 computers a UPS 650VA would last about 15 or 10 minutes, and so on.
