UPS uninterruptible power supply

UPS (Uninterruptible Power System), i.e., uninterruptible power supply, comprising an energy storage device, the constant voltage to the inverter as the main components of the constant frequency of the uninterruptible power supply. Mainly used for a single computer, computer network systems, or other power electronic devices to provide uninterrupted power supply. When the mains input is normal, UPS will be served after the mains voltage to the load, in which case the UPS power supply is an AC mains voltage regulator, while also charging the battery to the machine; when the electricity is interrupted, UPS Now the internal battery power, continue to supply through an inverter to convert 220V AC to the load method, the load to maintain the normal work load and protect software and hardware from damage.
