FSP's PSU plus BBU is an all-in-one power solution that integrates an AC/DC power supply, DC/DC charging and discharging circuits, and a BBU (Battery Backup Unit). It functions not only as the power source for end devices but also as an uninterruptible power supply (UPS) during power outages. It seamlessly switches to battery power when AC input is interrupted, providing stable power to ensure continuous operation, prevent data loss, and allow safe saving and shutdown if necessary. To learn more about FSP's PSU plus BBU solutions, check out the article "How an Innovative Power Supply with Battery Backup Unit (BBU) Improves Power Issues for ICT Equipment".

FSP’s PSU plus BBU can be used in the following devices:
A. Network equipment: such as routers and modems, to maintain stable network connections.
B. Industrial control systems: to ensure continuous operation of automated equipment and control systems in factories and production lines.
C. Home and office: to protect personal computers, home entertainment systems, and office equipment from power interruptions.
These scenarios require stable power supply to ensure uninterrupted service of end devices. FSP's PSU plus BBU provide temporary power during outages, ensuring smooth operation.

FSP’s PSU plus BBU and Uninterruptible Power Supply (UPS) fundamentally differ in product design and functionality. UPS is a product specifically designed to improve power quality issues and has been on the market for decades. It mostly uses lead-acid batteries to store power and is a widely used power backup mechanism. In contrast, FSP’s PSU plus BBU conceptually integrates UPS functionality into the power supply unit itself. It is a power solution that combines both power supply and battery backup mechanisms. For more information about FSP’s PSU plus BBU, you can refer to the article "How an Innovative Power Supply with Battery Backup Unit (BBU) Improves Power Issues for ICT Equipment" which helps you better understand this innovative power supply.

FSP’s PSU plus BBU can only provide power to dedicated end devices, unlike a UPS which typically offers multiple AC output sockets to provide emergency power backup for multiple devices. For power backup needs of a single end device, FSP’s PSU plus BBU can replace a UPS and offers specifications and functions superior to a UPS. However, in situations where multiple end devices require power backup simultaneously, using a UPS is more convenient.
