Power of the data center module
The technical room holds the power chain: the incoming supply, the architecture from single path to 2N, the conversion to -48 V DC and 230 V AC, the batteries and the distribution to every rack.
Input
400 V AC, 3-phase, 50 Hz, TN-S. The incoming supply is metered, and so is every load section downstream.
From N to 2N
The architecture is chosen per project: a single path (N) where the site accepts it, up to 2N with two independent A/B paths, a generator input and two automatic transfer switches in cascade. An emergency power off (EPO) is part of every configuration.
Conversion
A modular power system with guaranteed -48 V DC and 230 V AC outputs: hot-swap rectifier and inverter modules, and battery strings per side. Where the IT is pure AC, a conventional AC UPS takes its place.
Batteries
VRLA or lithium-ion, with the autonomy sized per project. A solar input through DC chargers is an option for sites with their own generation.
Distribution
Per-rack DC and AC distribution with fuse-switch disconnectors, optionally monitored PDUs, and metering on the incoming supply and on every load section. The power cabinets stand in the technical room, behind the EI 60 partition.

Questions procurement asks
Why -48 V DC?
Telecom and edge equipment is often fed at -48 V DC. The modular power system gives both -48 V DC and 230 V AC from the same rectifier and inverter modules, with battery strings per side.
Can we start with N and grow to 2N?
The architecture is set per project. A module designed for 2N can be delivered with one path populated; a module designed for N stays N.
Where do the batteries stand?
In the technical room, on the locally reinforced floor the specification names for battery cabinets, behind the EI 60 partition.
Send the rack layout. The module is engineered around it.
Rack count, width, depth and the density per rack set the room, the power architecture and the cooling. The specification sheet comes with the reply.

- Data CentersFactory-built data center modules for edge, enterprise and AI.
- Envelope and securityThe envelope is what the IT never notices: fire from outside held for 60 minutes, a burglar held at RC3, salt air held for decades, and a floor that carries the racks and keeps a leak inside.
- CoolingAir-cooled at 5 to 10 kW per rack as the typical design point, with the aisle contained and the room kept tight. Higher density and liquid cooling are engineered on request.
- Fire and monitoringClean-agent suppression in a room that is tested to hold it, detection that sees smoke before it is smoke, and a monitoring layer that reports every sensor over SNMP and Modbus.
- Process and factory testThe module is engineered once and built as many times as the programme needs. Before it ships it runs under a load bank in our plant, and the suppression system is tested in the room it protects.
