UPS (Uninterrupted Power Supply)
When planning business continuity, a centralised UPS is normally more powerful, functional, sophisticated and automated than a solution based on a distributed architecture. What’s more, it’s usually housed away from the main data centre. Distributed UPS, however, is simpler and less costly to install; vital equipment can be protected independently, and thus it is shielded from a central power outage. This standalone UPS (Uninterruptible Power Supply) situated at Stand Alone (solar) Power Systems provides back-up power for the oﬃce and workshop. With the advent of power failures this storm season, an UPS is ideal for complete back-up of computers, faxes, printers etc to keep you in business form halting. The UPS does not have to be a complex system, all it does is to provide enough power to run essential appliances from a few hours or several days, depending on how critical the application is. The one pictured here is over-engineered for its application, however can run the oﬃce
and workshop for 1 week with a blackout of the mains electricity. Standalone Power Systems can design and supply an UPS depending on your needs and budget, the charger can be installed on an oﬀ-peak tariﬀ to save costs. In this scenario only, oﬀ-peak tariﬀ chargers will be applied while you’ll have the additional beneﬁt of continuous, uninterruptible power.
A centralized UPS solution is where a single UPS is utilized to feed a dedicated ring main which supports numerous items of critical load. The alternative solution is a distributed / decentralized one, where each piece of equipment is powered by a smaller individual UPS.A centralized UPS system is normally, in terms of utilization of load and battery capacity, far more versatile and cost eﬃcient. However, the installation of a dedicated ring main can be expensive – especially if the items of load are widely spread throughout a building. While a distributed / decentralized
solution may not optimize load capacity and hold up time, the eﬀects of UPS failure are reduced when compared against the eﬀects of the failure of the centralized UPS.
