A datacentre located in Bern-Wankdorf and owned and operated by Swiss telco, Swisscom has been awarded the energy prize 'Watt d'Or' in the category 'Renewable energies' by a jury under the patronage of the Swiss Federal Office for Energy.
The jury said the datacentre is one of the most secure, modern and energy-efficient such facilities in Europe. Only outside air and rainwater is used for cooling. The operator has also abandoned the use of polluting refrigerants, and feeds its waste heat into the city council's new heating network.
Last summer, the Bern-Wankdorf facility was awarded Tier IV Design Certification by the Uptime Institute.
Euro-Diesel a terminé avec succès la mise en service de 4 systèmes de 2000 kVA qu'elle a livrés à SWISSCOM Immo pour son tout nouveau data centre.
Em 5 de agosto, São Paulo sediou o Data Center Infra São Paulo, evento que reúne conferência e área de exposição e objetiva reunir os principais profissionais da área e as novas tecnologias, disponibilizando informações e conhecimentos sobre construção, renovação e operação de data center. [PDF][+]
Many industries have a combination of critical (UPS) and non-critical (SB) loads in their facility. The NO-BREAK E1-SB is the perfect match to combine both load types by powering the critical loads at all times, and then powering the non-critical loads within a maximum of 10 seconds break.
The NO-BREAK E1-SB eliminates the need of additional diesel generators, saves on floor space and eventually, saves on building costs. As a result, this reduces the total Cost of Ownership.
The critical loads (UPS) are fed via the conditioned power of the DRUPS: Q2 is closed.
Non-critical (SB) loads are fed direct from the utility: Q5 is closed and Q6 is open. When a utility interuption occurs the breaker Q5 opens and within a maximum of 10 seconds, Q6 is closed to provide power to the non-critical loads via the diesel engine.
On mains failure, the critical loads are automatically protected at all times.
The introduction of a tapped choke in the electrical scheme provides an additional advantage: in case of a short-circuit on the non-critical busbar, the critical load will be unaffected since the choke will reduce the influence on the critical busbar.
Note : It is recommended that for all NO-BREAK E1-SB systems, the critical loads be larger than the non-critical loads.
Output power split example (in 60Hz):
1. UPS Critical load = 1500kW, total output power = 2000kW. Therefore the rating is 1500/2000kW.
Note: The above systems are also available in medium voltage.
