A loss of power can be of great cost to any business, resulting in significant loss of data or even damaged IT equipment.
The uninterruptible power supply (UPS) plays a crucial role here, safeguarding a data centre and ensuring services continue to run. It's essentially a very large battery, protecting your IT equipment, with two main functions- continuity of power and smoothing of power.
Continuity of power ensures that in the event of a mains power failure, your IT equipment stays on.
The smoothing of power encompasses protecting your IT equipment against surges- for example, from the national grid.
The UPS powers banks of batteries which ensure that during the 10-15 minutes of a power failure, the IT load is continually protected. This provides enough time for the generators to start up, which takes about ten seconds.
