Final answer:
A UPS will provide DC power to essential systems for approximately 15 minutes, acting as a backup power source during a power outage.
Step-by-step explanation:
The Uninterruptible Power Supply (UPS) will provide DC power to the system for uninterrupted emergency power to essential systems for approximately 15 minutes. A UPS is a device that acts as a backup power source when the main power supply fails. It uses batteries to store electrical energy and converts it to DC power, which can be used to power critical systems during a power outage.
For example, in a computer system, a UPS can provide power to the computer and other connected devices, such as a modem or router, allowing them to continue operating for a limited time without interruption. This gives users enough time to save their work and properly shut down the devices to prevent data loss or damage.
It is important to note that the actual backup time provided by a UPS depends on various factors, such as the capacity of the batteries, the power consumption of the connected devices, and the load on the UPS. In some cases, a UPS may be designed to provide longer backup times by using additional batteries or larger capacity batteries.
