Developments In UPS Technology: Choosing The Right UPS For Data Centres

No matter whether a company uses its own data centre or relies on the computing and storage capacity of a cloud computing provider, tough demands are always placed on availability. Therefore, an uninterruptible power supply (UPS) is essential to compensate fluctuations in the supply voltage and filter out interference. Choosing the right system not only determines the security of the services on offer but also plays a key role in the operating costs that are billed at the end of the month. Please find attached a technical article from Rittal exploring this topic.

Every company needs to consider the computing and storage volume of its data centre. It's important to be able to compensate for the variability of supply voltage and separate out interference with an uninterruptible power supply (UPS). A company should get a UPS system that can determine the security needs of the service and be a major part of monthly operating costs. The UPS PMC 12 | Single-phase, output range 1-12 kVA n+1 | has double-conversion technology and is the basis for optimal supply voltage to all connected loads.

When choosing a UPS system it's imperative to consider the many different factors involved when determining which one best meets a company's needs. One of the most important things to do is have a risk assessment performed. Companies need to be completely aware of the extent downtime will affect their operations. A survey conducted by PricewaterhouseCoopers showed that 15 percent of the companies surveyed estimated that any downtime could easily cost their operation up to $1.25 million or more. The UPS PMC 40 | 3-phase, output range scalable 10-40 kW | PMC 40 has a compact rack-independent UPS system (up to 40 kW, 3-phase). This UPS also uses double conversion technology.

A UPS system is able to easily handle brief power failures of a few minutes. This is important since 90 percent of all common power failures last fewer than two minutes. Preparing for scenarios that could cause large data centres to go many hours without power may require the use of a diesel generator. This will increase cost but may be worth it depending on how critical the data centre function is to the operation. The UPS PMC 120 | Modular UPS System (up to 120 kW) | UPS power modules is designed to operate on the double conversion principle (classification to VFI-SS-111).

It doesn't matter if a company has its own data centre or utilizes the storage function of a cloud computing supplier. In the future UPS systems will be accepted as an important part of every company's server room and data centre. The UPS PMC 200 | 3-Phase, outage range scalable 8-1200kW | Rittal PMC 200 ensures optimum availability and combines modularity for critical applications.
