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 |
