An Uniterruptible Power Supply, or UPS, is required when the AC power that runs sensitive equipment is not reliable or not well regulated or filtered. During power brownouts or blackouts the UPS can provide AC power to the equipment, such as computers or emergency lighting, for a period of time, usually until normal power source is restored. Most UPS circuits include some or all of the system blocks shown above.
