What Is an Uninterruptible Power Supply (UPS)?
Three main types of uninterruptible power supplies are currently used: offline, line interactive, and on-line systems. Offline UPS systems are standby systems that provide battery power to equipment when the main power supply falls underneath a certain limit. These are mostly used in home and office applications due to their lower cost.
Power outages and electrical fluctuations can cause serious disruptions, whether you're working from home, running a business, or using a gaming PC. An uninterruptible power supply (UPS) helps prevent sudden shutdowns, data loss, and hardware damage by providing backup power when your main electricity fails.
