It is important to protect sensitive electronic equipment such as computers from fluctuations and cuts in the power as unexpected loss of power can cause permanent damage to components and data loss. A UPS will act as a surge protector, battery backup and generally “smooth” out the power your computer receives and ensure maximum stability. UPS devices are normally found attached to expensive mission critical workstations (such as graphical workstations or CAD machines) or servers where any downtime is unacceptable. UPS systems work by detecting decreases in the amount of electricity coming from the wall circuit and then boosting power to maintain a constant flow of electricity to the connected equipment. This power boost is achieved either from an internal transformer than enhances the electricity supply or from an internal battery that substitutes for the normal power source in the event of power failure.

What is the point in a UPS? It is important to protect sensitive electronic equipment such as computers from fluctuations and cuts in the power as unexpected loss of power can cause permanent damage to components and data loss. A UPS will act as a surge protector, battery backup and generally “smooth” out the power your computer receives and ensure maximum stability. UPS devices are normally found attached to expensive mission critical workstations (such as graphical workstations or CAD machines) or servers where any downtime is unacceptable. How do UPS devices work? UPS systems work by detecting decreases in the amount of electricity coming from the wall circuit and then boosting power to maintain a constant flow of electricity to the connected equipment. This power boost is achieved either from an internal transformer than enhances the electricity supply or from an internal battery that substitutes for the normal power source in the event of power failure. What types of UPS are available? There are three major types of UPS available in the market, each with their own advantages and cost. Off-Line Units: Off-line units switch from the regular power source to an internal battery when there is a power drop. There is a brief delay between the time the power drops and the time the battery starts supplying power. However this downtime should be brief enough to avoid causing the computer to shut down. On-Line units are normally the cheapest UPS products available. Line-Interactive Units: Line-interactive units add a transformer to minimise the need for an internal battery to be used with every power fluctuation. These units monitor the line voltage at all times and active the power transformer when the voltage falls below certain parameters. The battery is only ever activate when lower voltages are recorded. There is a brief delay between the time the power drops and the time the battery starts supplying power. However just like the Off-line units this downtime should be brief enough to avoid causing the computer to shut down. On-Line Units: On-line units constantly supply power to the connected PC from their internal battery; the battery is constantly charged...
