    UPS by Type

    What is an Uninterruptible Power Supply (UPS)?

    An Uninterruptible Power Supply (UPS) is an electrical device that can provide backup power to other electrical devices when there is a power outage or voltage drop. The UPS functions to adjust the voltage to an appropriate level and supply power from the battery to the electrical devices continuously.

    Benefits of a UPS

    A UPS has many benefits, including:

    • Prevents damage to electrical devices from unstable power supply, such as voltage drops or surges.
    • Allows electrical devices to continue operating even during a power outage.
    • Enables timely saving of work in progress during a power outage.
    • Ensures continuous operation without interruptions.

    Types of UPS

    UPS can be categorized into different types based on their operation mode, such as:

    • Offline UPS or Standby UPS: The most basic and least expensive type, which operates by supplying power from the main power source. When a power outage or voltage drop occurs, the switcher switches the power supply to the battery.
    • Line Interactive UPS: Developed from the Offline UPS with an added Automatic Voltage Regulation (AVR) system to maintain the voltage at an appropriate level.
    • True Online UPS: The highest performance type that can protect against all electrical problems, including power outages, voltage drops, surges, or any interference.

    Choosing a UPS

    When choosing a UPS, consider the following factors:

    • Power capacity: Choose the UPS power capacity suitable for the power demand of the electrical devices to be used.
    • Backup time: Choose the UPS backup time that is sufficient for the operation of the electrical devices.
    • Type of UPS: Select the type of UPS suitable for the application.
    • Other features: Such as surge protection system, battery low warning system, etc.

    Maintaining a UPS

    To extend the life of a UPS, maintain it as follows:

    • Clean the UPS regularly.
    • Regularly check the UPS battery.
    • Replace the UPS battery when it deteriorates.


    A UPS is an essential electrical device for daily use, helping to prevent damage to electrical devices from unstable power supply and ensuring continuous operation without interruptions.
