It regulates temperature within the centre

It provides backup power during outages

The function of a UPS (Uninterruptible Power Supply) in a data centre is to provide backup power during outages. This is crucial in maintaining the operation of critical systems, servers, and network equipment when the primary power source fails. A UPS ensures that there is uninterrupted power, allowing for a safe shutdown of systems or continued operation for a limited time, which helps prevent data loss, corruption, or hardware damage.

In addition to backup power, a UPS also typically offers power conditioning, protecting sensitive equipment from fluctuations and surges in power supply. The ability to maintain power during outages is essential to ensure the reliability and availability of services, which is at the heart of data centre operations. This capability supports business continuity and protects against the disruption of services that could impact customers and operations.
