What Types Of Ups Are There?

What types of Uninterruptible Power Supply(UPS) are there? They are mainly divided into three types: online, backup, and online interactive. Online UPS is like a full-time bodyguard, always ready to provide stable power for the equipment; backup UPS is like a part-time bodyguard, only available when the mains power is off; and online interactive UPS is somewhere in between, providing stable power when the mains power is normal, and providing battery power for a period of time when the mains power is off. In addition, for some equipment that needs to run 24 hours a day, such as surveillance cameras, medical equipment, etc., UPS power supply is even more indispensable.
