Advantages of an Uninterruptible Power Supply

Uninterruptible power supplies (UPS) offer advantages that make them attractive investments for individuals and businesses alike. Although the most obvious advantage of an uninterruptible power supply is the maintenance of power to electronic equipment such as computers and routers in the event of a power outage, the UPS offers other important advantages.
Continuity of operation is the most basic feature a UPS offers. When plugged into an AC wall outlet, the UPS unit maintains a charge on its batteries during normal operation. Built-in electronics sense when external power is not present and switches the UPS output from wall power to AC power produced through its batteries and built-in inverter. By switching to battery power, UPS devices prevent momentary power glitches from resetting equipment and – in the event of a long term outage - give operators the chance to shut down equipment in an orderly and safe manner. The result of the proper operation of a UPS is higher productivity and less data loss.
An enhanced form of UPS, the line-interactive UPS, serves to clean its incoming power before sending it to its output. These units use components called autotransformers to adjust the voltage sent to the output, reducing the impact of unstable AC power sources that are chronically under or over voltage. By actively adjusting its output, the line-interactive UPS is able to make sure that computers and other connected gear are not subject to systemic power fluctuations that can cause failure.
Also significant among the advantages of an uninterruptible power supply is the so-called “online” UPS. Although this kind of UPS usually costs more than a basic standby unit, it offers the most benefit when sensitive equipment is in use. This kind of UPS always powers its internal battery source. Although it uses the incoming AC to keep the batteries charged, the AC output is always safe, taking the condition of the input AC power completely out of the equation. This guarantees that the power sent to attached devices is always free from noise and damaging wave forms as well as from outages, spikes, and surges.

Power Protection said...

Definitely there are many advantages of uninterruptible power supply and there is hardly any doubt about the importance of a UPS power supply. We all know that these days the role of UPS systems has grown significantly as it protects your damages from electrical power disturbances. In addition to provide the protection against complete failure of the utility supply, UPS systems also keep computers and other appliances protected from other power related problems. These power protection systems are available in the market by different names like continuous power supply, UPS battery backup, uninterruptible power source and the list goes on.
