Electrical installations

Guaranteed power 10 MVA
Compatibility Surge protectors, protection against over voltage and residual currents
Powr transformation Transformer station middle voltage to low voltage on site (5x2500 k/VA transformers, N+1), at a sufficient distance hosting and telecom rooms (electro smog)
Power distribution Double power grid distribution with seamless switching <10 ms through modules charge transfer (STS). Each rack is connected via rail energy on two separate switchboards (N+N redundancy)
UPS Power Each branch is protected by dynamic inverters kinetic energy storage (5 Nobreak of 2500 kVAN +1 redundancy). All systems are powered with uninterruptible cooling
Power backup Each electrical power distribution branch is protected by a diesel generator (5 groups of 2’500 kVA directly related to dynamic, N+1 redundancy), each supplied redundantly fuel (2 main tanks + 5 daily tankers a total of 160;000 liters stored on site, corresponding to 80 hours of power consumption at full load, with additional supply program):


Production 4 turbo compressors groups of 2500 kW (redundancy N+N), 2 free-cooling exchangers to use external cold air
Distribution Double distribution network of ice water (redundancy N+N)
Air conditioning units 50 kW per unit for liquid cooling (N+N redundancy), 55 kw per unit for cooling ventilation located outside of the holding rooms (N+1)
Electrical power supply All power systems production and distribution of cooling and air conditioning units are located behind uninterruptible power supply
