What is the difference between centralised and decentralised UPS systems?

If you have been trying to choose between centralised and decentralised UPS systems, you may wonder how these two systems compare. While each type of system has its own use, one may be a more cost-effective and efficient solution than the other. Depending on the size of your premises and a few other factors, you may find that one or the other will work best or you may find that a combination of the two is the best choice rather than choosing just one system.

Before we share some of the biggest benefits offered by both centralised and decentralised UPS systems respectively, the first step is to consider your requirements. One thing to consider carefully is the cost. Centralised systems typically require less maintenance with a high efficiency rating, making them a cost-effective solution. Installation costs are typically lowered for a decentralised system, however, as there is no need for support staff and special electrical outlets. Reliability is another factor to consider. In some cases, centralised UPS systems can be more reliable, however, they are not always immune to single-point-of-failure as resources are confined to a single point. It is also worth considering capacity requirements further down the line as well as space, which can affect both types of systems depending on how much space you have available.

Centralised vs decentralised UPS systems

Now that you have taken these factors into account, how do centralised and decentralised UPS systems compare?

Centralised systems…
  • Have a longer sales and service life
  • Are often easier to monitor and maintain over multiple units
  • Are usually kept away from high traffic areas, reducing disruption
  • Can be kept in a location with controlled cooling
  • Have easy to replace batteries with a single battery to replace
Decentralised systems…
  • Do not require any additional wiring
  • Use existing wall sockets
  • Have an easy installation for instant plug and play
  • Have lower installation costs
  • Implement power conditioning to reduce electric disturbances

Both of these systems can be used within a building when it comes to powering critical applications. Smaller departments may use smaller decentralised units while the entire building might use a large centralised unit. Choosing the system that best suits your needs is the most effective way to maintain power at all times, whether using centralised or decentralised UPS systems or a combination of both.
