Offline UPS: Offline UPS separates the battery from the inverter, and the inverter is responsible for converting the mains power into AC power to supply the equipment. When the mains power is interrupted, the offline UPS will immediately switch to battery powered mode. The conversion time of offline UPS is relatively long, usually ranging from a few seconds to tens of seconds. Offline UPS is usually used for devices that do not require high power quality, such as home computers, printers, etc.
Backup UPS: The backup UPS directly provides AC power to the equipment connected to the load. When power is lost, the backup UPS will change the position of the transfer switch. It connects the load to the battery backup path. Backup UPS
The backup UPS battery charges when AC power is available. In this case, the AC power is directly input into the load circuit, while the battery of the backup UPS is charged through the rectifier circuit.
Online interactive UPS: Online interactive UPS is structurally similar to backup UPS. The only difference between them is that the line interaction includes an automatic voltage regulator along with EMI and RFI filters. Automatic voltage regulator eliminates voltage fluctuations while suppressing voltage fluctuations. In summary, UPS, as a critical power protection system, is of great significance in ensuring the normal operation of critical equipment, protecting data security, and improving business continuity. Different types of UPS have different performance and application scenarios, and users should choose the appropriate UPS product according to their own needs.
