2kVA UPS Prices and Specifications

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.
