A major uninterruptible power supply contract has been completed by Square One Power Solutions for the protection of the data centre at the new Umhlanga Rocks corporate headquarters of healthcare administrator Sovereign Health.
Square One Power Solutions, the UPS specialist in the JSE-listed Square One Solutions Group, has installed and commissioned three 120kW UPS units in a parallel redundancy configuration for Sovereign Health that ensures maximum protection and minimal risk. The total load is shared among the three units, providing spare capacity so that should one of them be taken offline for servicing or adjustment, the other two can take up the entire load so that there is no disruption of supply to the data centre.
A purpose-made power distribution panel was also installed. This makes allowance for the future installation of a fourth 120kW UPS unit without interrupting the existing load.
Square One Power Solutions Durban branch manager Charles Bott says power failure interruption of corporate data centres can result in disruption of business operations and corruption or loss of data, both of which have significant financial loss implications.
"The contract demonstrates the importance that companies place on having uninterruptible power supply (UPS) systems in support of critical corporate data centres."
The power system solution installed for Sovereign Health is based upon APC Silcon UPS equipment offering three-phase online power protection and ensuring high security of power supply.
Square One Power is an APC Hi-Power Partner and Bott says the design of the APC Silcon units caters for modern downstream loads. As a result of new overseas standards, computer loads are tending towards unity power factor inputs, which result in increased power demand from the UPS unit.
Bott says APC units function over wide voltage and frequency ranges and are compact, small footprint products that have a unity input PF and work at 95% efficiency with less than 5% input harmonic distortion. "They handle crest factors of up to 10 to one as well as overloads of 200% and because of their inherent high specification, they are diesel generator set-friendly and most cost-efficient."
