Electronic UPS

An electronic UPS (uninterruptible power supply) is a device that provides emergency power to a load when the input power source, typically mains power, fails. It is an electrical apparatus that provides emergency power to a load when the input power source, typically mains power, fails. It is typically used to provide backup power to computers, servers, and other electronic equipment. It is also used to provide power to critical loads during a power outage. The UPS typically contains a battery, a rectifier, an inverter, and a control circuit. The battery provides power to the load during a power outage, while the rectifier converts the AC power from the mains to DC power for the battery. The inverter then converts the DC power from the battery to AC power for the load. The control circuit monitors the input power and switches between the mains power and the battery power as needed.
