![]() The transfer time generally occurs in milliseconds after a power loss, and although the switch is not instantaneous, in most cases it will not interrupt the flow of power to equipment. A standby UPS will switch to battery to safeguard connected equipment when power fails, as well as adjust for routine sags and surges. In a standby UPS model, connected devices receive utility power through a direct AC connection, with the unit essentially remaining on hold until backup power is needed. ![]() Standby UPSĪlso referred to as an offline UPS or passive UPS, standby technology offers the most basic type of protection, allowing equipment to run off of incoming utility power until it detects a problem. Each type of UPS topology not only delivers varying levels of protection against power problems but achieves the result in a separate manner while placing differing frequency demands on the battery. Rather, there are three primary topologies: standby, line-interactive and online. It’s important to understand that all UPS systems are not created equal. In addition to delivering backup power during a utility failure, UPSs also afford varying degrees of protection against other damaging power problems, including voltage sags, surges, brownouts, line noise, frequency variations, overvoltage conditions, and switching transients and harmonic distortion. Essential for mission-critical environments, a UPS keeps computer systems and IT equipment safe and operational during a power loss until generators can be activated or protected devices such as servers and network components can be properly shut down, preventing loss of data and work-in-progress. In case of a blackout, the UPS immediately switches to battery to provide a continuous power source for the length of the battery, which varies by system for periods of time ranging from minutes to hours.ĭepending on the size and technology of the unit, a UPS is capable of protecting a single computer up to an entire data center. How Does a UPS Work?Įssentially a battery in a box, a UPS powers the devices that are plugged in to its AC outlets when the flow of electricity drops to an inadequate voltage, or if a complete outage occurs. Depending on the UPS model, these systems also shield connected devices from common power problems and unsafe output voltage fluctuations that can damage electronics, reduce lifespan and affect performance. But protecting equipment against a complete power loss isn’t the only reason you need a UPS. By supplying an adequate window to safely shut down sensitive equipment, a UPS helps prevent data loss and minimizes the stress of a hard shutdown on electronics. What Is a UPS?Ī UPS is a backup system that provides power in the event of a utility failure. ![]() But with several different types of systems available, the challenge is selecting the one that best matches your needs and budget. Thankfully, an uninterruptible power system (UPS) is one of the most simple, cost-effective solutions to help companies avoid the unwelcome consequences of downtime. Not only is the current price tag for downtime estimated at $5,600 per minute, but unplanned incidents can result in equipment damage, data loss, missed opportunities and tarnished reputation. Even the briefest amount of downtime can be devastating to an organization, regardless of its size or vertical. Across today’s highly connected and data-driven business landscape, the need for continuous, clean power cannot be overstated. ![]()
