40kVA rated UPS systems for server rooms, datacentres and other critical environments. The UPS are rated at 40kVA and their kW-rating will vary depending on their output power factor. Monoblock UPS can be operated in a parallel/redundant N+X configuration to provide additional resilience. Modular UPS if available are shown with by their UPS frame sizes. Battery runtime options may include internal battery sets and external battery cabinets and racks for longer runtimes.
Server Room Environments provides a complete electrical installation service for 40kVA/40kW rated UPS systems by NICEIC certified electrical contractors. The installation service covers every aspect you could need in a UPS installation.
Standby Power Generators
The installation of a local standby power generator can be used to provide a 40kVA/40kW UPS with additional runtime up to 8 hours or more using a stored energy source including diesel or liquid petroleum gas. The generator and alternator will need to be sized for the UPS with a typical recommendation of 1.25 times the size of the UPS system.

Edge computing coupled with 5G mobile wireless technology promises to be the next stage in the 5th industrial revolution and to provide the bridge to many new services, some of which are still ideas in their nascent stage of ‘if I had an App for this…’
There are several key choices to make when it comes to selecting the right uninterruptible power supply to install with a server rack. These include not only the topology but the load size, form factor, runtime, access for maintenance and connectivity.
Power supply design is one of the key decisions that must be taken whenever building a new server room or refurbishing and existing one. There are several elements to consider even for a single stack rack cabinet if you are to ensure that your server installation can run through power outages.
The critical power path in a server room, datacentre or other type of network environment is the path from the building incomer (mains power supply) to the critical load connection socket or terminal (PDU). Elements within the critical power path can include LV switchboards, UPS systems and standby power generators, transformers, sub-distribution panels, power distribution units, fused spurs and socket outlets.
Power factor is the ratio of Real Power (W) to Apparent Power (VA) in an AC circuit. Power Factor corresponds to the phase-angle difference between the load drawn voltage and current waveforms.
Power factor is shown as a decimal number or percentage i.e. 0.65pF = 65% between 0-1pF and 0-100% respectively.
Power Factor formulae include:
Power Factor (pF) = Real Power (W) ÷ Apparent Power (VA) = CosØ
If we know the Power Factor and Real Power we can calculate:
Apparent Power (VA) = Real Power (W) ÷ Power Factor (pF)
If we know the Apparent Power and Power Factor we can calculate:
Real Power (W) = Apparent Power (VA) x Power Factor (pF)
Edge computing pushes data processing nearest to the device that needs the information to operate, rather than pushing the data back to a centralised datacentre. Edge computing is essentially a de-centralised approach. In terms of power protection to ensure resilience in an entire decentralised eco-system it is important to protect both the servers within the cloud datacentre and each data-processing point along the Edge computing network. Larger three phase UPS systems may be required for datacentres with far smaller uninterruptible power supplies required for small load servers, PCs and Internet of Things (IoT) devices.
