Redundant power refers to a technical means of adding a backup power source to a power system to ensure that power continuity is maintained when the primary power source fails. Redundant power supplies are usually applied to critical equipment and systems with extremely high power requirements, such as medical equipment, nuclear power plants, and data centers. Redundant power supply is a technical means of backing up through multiple power supply modules, adopting a hot-standby plug-and-play design to enable the backup power supply to start automatically when the main power supply fails, thus ensuring uninterrupted power supply.
The role of redundant power supply is to ensure that critical equipment can still work normally when the main power supply fails, avoiding problems such as system crash and data loss due to power interruption.
