UPS

For mission-critical applications that require uninterrupted power, for example in industry or hospitals, it’s essential that the right standby power generation equipment is in place. With power grids having more and more demands placed on them, the continuity of mains supply can never be guaranteed. Mains power can also be lost due to downed lines, malfunctions at a sub-station, inclement weather, planned blackouts or in extreme cases a grid-wide failure.
Computers, communication networks and other modern electronic devices need not only power, but also a steady flow of it to continue to operate. But if the source voltage drops significantly or drops out completely these devices will fail, even if it is for a fraction of a second. Because of this, even a generator back-up does not provide protection because of the start-up time involved. To achieve this, extra equipment such as uninterruptible power supply (UPS) is used. UPS systems can be local or building wide. A local UPS is a small box that fits under a desk or a telecom rack and powers a small number of devices. A building wide UPS can take on several different forms, depending on the application. It directly feeds a system of outlets designated as UPS feed and can power a large number of devices.
