Uninterruptable power sources provide mechanical and digital machines with interim power in a broad range of industries, including manufacturing, information technology, transportation and healthcare. Techopedia Explains Uninterruptible Power Supply This type of UPS protects the critical loads from virtually all power disturbances and is the most common UPS used for protecting large data centers and other critical equipment. Line interactive UPSes can provide moderate protection against power fluctuations, as well as battery backup.ĭouble-Conversion Online: This is similar to line-interactive, except that a rectifier directly drives a DC/AC inverter, even when it is powered by a normal AC current. Line-Interactive: Ensures power for five to 30 minutes and up to several hours with expansion, by using a multi-tap, variable-voltage autotransformer, which immediately adds or subtracts the a transformer’s output voltage. This type of UPS is best suited for backing up low power devices, such as small office workstations and personal home computers.
APC BACKUP MEANING OFFLINE
Offline UPS provides battery backup but doesn’t maintain perfect power during sags and surges. Offline/Standby: Restores power when normal power fails by using a DC/AC inverter output that is usually no longer than 25 milliseconds. The size and capabilities of a UPS system depends on the protected equipment size, which can range from a single computer to a large data center, building complex or city.
All types of UPS systems are designed to keep power levels consistent and prevent fluctuations that could harm digital or mechanical equipment, but there are different design types to provide different levels of protection. The purpose of a UPS is to keep power levels consistent and prevent fluctuations that could harm digital or mechanical equipment.
