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):


INSTALLATIONS

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


SLA
