Power supply

A stable and highly available power supply is one of the three important pillars in the operation of a computer center. The other two being the network connection and air-conditioning

Our power supplies are provided by our own transformer stations with 6 × 1-MVA-transformers, which are directly supplied from the substation with medium-voltage (12 kV). The supply of customer racks is continuously carried out (Feed A+B), just as USV and emergency power systems (diesel generators).

Through the permanent monitoring of all critical components and regular and intensive examinations of all parts, our infrastructure ensures that a possible power failure is bridged through the batteries, the diesel motors start and a long term power supply is guaranteed.

• Power through our own 6-megawatt transformer station
• Redundant feed-in from two independent district stations
• Redundant USV and emergency power systems (n+1)
• Redundant power supply per rack with Feed A+B
• Power circuits available with 230V and 400V
• Availability at least 99.99% in the annual average
• Power up to 100% from CO2-neutral production
• Monthly test of all diesel generators under full load
• Annual black building test
