Safeguarding critical power supplies

Paul Boughton

Investing in the right uninterruptible power supply (UPS) solutions is becoming vital for industry and commerce at a time of economic uncertainty and doubts over future energy security.

As the world becomes more IT dependent, the performance of data centres and smaller data hubs is crucial, with data centre managers under increasing pressure to meet enhanced efficiency targets to cope with escalating energy prices and the threat of increased power outages in the UK in the future.

One company helping this sector achieve their targets and safeguard against any power failures is leading high performance UPS manufacturers, Borri Ltd.

For new builds and data centre hubs in particular, there has been a stark rise in demand for more flexible, modular UPS solutions, which have proven to be highly cost effective by lowering the initial investment, allowing operators the flexibility to invest in their data centre as it grows.[Page Break]

Borri has responded to the need for more flexible back-up power protection solutions with the latest addition to the company's UPS range, The Primacy, achieving ground-breaking efficiency of up to 99.5 per cent. The Primacy is a transformer free solution, which is modular, scalable and combines three sophisticated modes of operation.  

The highest levels of efficiency are achieved in Ultra High Efficiency mode (UHE), where advanced design of internal power components enable the UPS to operate silently with natural cooling for 99.5 percent efficiency.

At part load, in online double conversion mode (VFI), the UPS reaches up to 96 per cent efficiency. For added power protection the UPS also uses the inverter as an active filter while in UHE, which provides compensation should the load have any reactive or harmonic content. The filter can also protect the load from mains disturbances. [Page Break]

The Primacy also delivers a unity output (kVA = kW) providing 25 per cent more power compared to UPS with PF = 0.8 and 11 per cent more compared to UPS with PF = 0.9, and combined with the Primacy's ultra slim design, allows users to achieve maximum power density.

In the case of large established data centres, where many carry traditional ransformer-based UPS systems and are now looking to extend or upgrade heir equipment with more efficient solutions, Borri's three phase ECO 9000 and B9600 range provides reliable back-up power and can reach an mpressive operating efficiency of 95 per cent, whilst in true on-line ode.

Borri's ECO-UPS range comes with an impressive 0.99 input power factor PF), giving improved efficiency and stability of the overall transmission etwork and a THDi of less than three percent to help eliminate any current istortion.

These high performance UPS solutions also come with the added benefit f being maintained without transferring the load to bypass mode, which ould expose it to unconditioned power.[Page Break]

Whilst both transformer-based and transformer free solutions from Borri eliver impressive efficiency gains, it is important for data centre managers to understand the limitations and advantages of available technologies as well as being able to identify how these are directly significant to their operational environment.
