P&R Morson & Company Ltd

Power Control help to complete a prestigious contract worth over £6.5 million.

Integrated building services maintenance provider P & R Morson & Company Ltd, has turned to leading uninterruptible power supply (UPS) specialists Power Control to help it complete a prestigious contract worth over £6.5 million.

The state-of-the-art facility, which houses approximately 1400 employees, was meticulously designed to be as energy efficient as possible and the council hopes to reduce carbon emissions by over 1750 tonnes in its first year. It was, therefore, essential to ensure that the dedicated data centre also met high-efficiency targets.

The solution and results

Due to the requirements, Power Control provided P & R Morson with a full turnkey service, supplying and installing four high efficiency Borri B9000 160kVA UPS systems in a tier four configuration, which are now providing vital power supply back-up for all IT and critical information stored at Staffordshire County Council’s new headquarters.

Featured on the prestigious Energy Technology List, Borri’s sophisticated B9000 FXS UPS range is one of the most efficient, affordable true on-line double conversion systems on the market. The four UPS systems were installed in parallel, with two on the ‘A’ supply and the others on ‘B’ supply. This tier four configuration gives ultimate levels of reliability and maximum flexibility and can be scalable up to eight units on both supplies for future expansion or further redundancy.

Installed to meet an extremely demanding specification, the new transformer-based UPS systems with redundant battery strings required a crane to transport them to the 10th floor of the new build data centre and were then positioned on open battery stands. Borri’s in-house DC battery build team were also on hand to deliver and install the batteries.

To ensure a path of UPS power is always available to the critical load, the electrical arrangement chosen was a 2N+1 configuration. Built to withstand equipment failures and disruptions without impacting essential computing assets, the data centre now has the greatest electrical protection and comes with an impressive 0.99 input power factor (PF), giving improved efficiency and stability of the overall transmission network and a THDi of less than three percent to help eliminate any current distortion. of the electrical infrastructure that have been suseptible to mains power fluctuations. Deployed to work independently, each Borri Ingenio UPS system has been sized to cope with maximum inrush currents and all include separate bypass switches.
