What are the advantages of a Centralised UPS solution when compared against a Distributed UPS Solution?
A centralised UPS solution is where a single UPS is utilised to feed a dedicated ring main which supports numerous items of critical load. The alternative solution is a distributed / decentralised one, where each piece of equipment is powered by a smaller individual UPS.
A centralised UPS system is normally, in terms of utilisation 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 / decentralised solution may not optimise load capacity and hold up time, the effects of UPS failure are reduced when compared against the effects of the failure of the centralised UPS.
