An uninterruptible power supply (UPS) is a device that provides emergency power to a load when the input power source fails. UPSs are used to protect critical equipment from power outages, surges, and spikes.
UPSs are available in a variety of sizes and configurations to meet the needs of different applications. Small UPSs are designed to protect individual computers and other small electronic devices. Larger UPSs can protect entire data centers and other critical infrastructure.
