An Uninterruptible Power Supply (UPS) is a device that provides emergency backup power to IT equipment during power outages. In data centres, UPS systems ensure continuous operation of servers and critical systems, preventing data loss and minimizing downtime. UPS units use batteries or flywheels to provide short-term power until generators or alternative sources are activated. High-tier data centres often deploy redundant UPS configurations to ensure reliability.
UPS systems typically provide power for a few minutes to hours, depending on their capacity and the load being supported.
They protect critical systems from power disruptions and allow safe transitions to backup generators.
Types include static UPS, rotary UPS, and modular UPS, each suited for different power demands and redundancy requirements.
