Critical power protection for medium to large Data Centres

Value proposition

• The data centre market is the largest market for critical power applications
  
• Data centres are also a large contributor to CO2 emission (1.5% of US power) and this is constantly increasing.
  
• Electricity costs are also a key contributor to the CAPEX of a data centre.

• Critical Power Protection for Medium to Large Data Centers with high efficiency.
• Including Uninterruptible Power Supplies (UPS), Source Transfer Switches, Synchronisation Modules, etc.
  
• Working according to recommended architectures towards optimum dependability.

• UPSs and associated equipment form high-availability configurations that are assembled in architectures compliant with the required availability standards (from 99,9979% to 99,9999% ("six nines")).
  
• UPS being in redundancy, they are not 100% loaded and it is critical to maintain high-efficiency of the UPS even at low loads.  Galaxy 6000 has a 92% efficiency even at 25% load ; at 500kVA a 2% efficiency level gain is worth €50,000 over 5 years in electricity cost!
• On non-linear loads the THM option can help save an additional 20% on the electricity bill
  Differentiation factors
  
• Thanks to the combination of high efficiency at low loads, and predefined architectures compliant with the de-facto "Tiers" levels, these systems provide an optimum combination of certified high availability and energy savings.
