An uninterruptible power supply or uninterruptible power source (UPS) is an electrical apparatus that provides emergency power to a load when the input power source or mains power fails. A UPS differs from an auxiliary or emergency power system or standby generator in that it will provide near-instantaneous protection from input power interruptions, by supplying energy stored in batteries. The on-battery run-time of most uninterruptible power sources is relatively short but with the correct design, the customer is insured to have back up power for specific appliances and equipment during short periods of power failure or during load shedding.

A UPS is typically used to protect hardware such as computers, data centres, telecommunication equipment or other electrical equipment where an unexpected power disruption could cause injuries, fatalities, serious business disruption or data loss. UPS units range in size from units designed to protect a single computer without a video monitor (around 200 volt-ampere rating) to large units powering entire data centres or buildings.

We supply and install various back-up systems to suit the specific needs of our clients. These systems can be designed to be scalable in future for expansion and extra power demands.
