2kVA UPS systems available from Server Room Environments include line interactive and on-line uninterruptible power supply systems. 2kVA UPS will be rated at 2000VA and have different output Watts rating dependent upon the power factor used by the UPS manufacturer. Please check the individual products for their kW rating. The output connections can be plug and play or hardwired dependent on the model which can be available in free standing tower or 19inch rack mount formats with options for extended battery runtimes. 2kVA UPS have tower or rack mount or a dual installation format and are designed to protect workstations, servers and IT network peripherals including Internet of Things (IoT) applications. The UPS have IEC-type output sockets as standard.
2kVA UPS typically provide IEC type sockets and can be plugged into a PDU or mains power socket. 2kVA UPS for hardwired connection are available on application.
Longer Battery Runtimes
The UPS will have an internal battery. Some 2kVA UPS have an external battery pack connector for longer runtimes. The amount of battery runtime available is dependent upon the load placed onto the UPS and the age, battery charge % and ambient environment.
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.
