Uninterruptible power supply(UPS)

  • Four operating modes of UPS

    Four operating modes of UPS

    Aug , 23 2024
    1、Normal operation mode The principle of the power supply system is that when the utility power is normal, the machine will convert the alternating current of the utility power to direct current, and then charge the battery for use when the power is interrupted; it is emphasized here that the power supply system will not only act when the power is out, such as when the voltage is too low or high, ...

  • How to extend the power supply time of uninterruptible power supply (UPS)

    How to extend the power supply time of uninterruptible power supply (UPS)

    Aug , 03 2024
    There are two ways to extend the duration of an uninterruptible power supply： 1. Increase battery capacity. According to the length of time required to increase the number of batteries, but this method will cause a relative increase in battery charging time, but also increase the number of corresponding maintenance equipment, increase product size, resulting in an increase in the overall cost of U...

  • Voltage drop calculation formula

    Voltage drop calculation formula

    Jul , 19 2024
    Voltage drop is a common issue in circuits. To calculate the decrease in voltage, we can use the following formula: Vout=Virn * (R2/(R1+R2)). This formula is based on the principle of resistance voltage division, where Vin represents the input voltage, Vout represents the output voltage, R1 represents the resistance value of the upper resistor, and R2 represents the resistance value of the lower r...

  • What are the meanings of deep discharge and excessive discharge of UPS batteries

    What are the meanings of deep discharge and excessive discharge of UPS batteries

    Jul , 11 2024
    Deep discharge generally refers to the discharge of approximately 80% of  the rated capacity of a battery. After a period of use, there will inevitably be some active substances sinking in the power UPS power battery. If the active  substances are not activated in a timely manner, it will inevitably have some  impact on the capacity of the battery. Therefore, it is best to cond...

    Explanation of terms related to UPS power supply

    Jul , 06 2024
    Transient Recovery Time: The time it takes for the output voltage to return to the specified range when there is a sudden change in load (0‐100%, 100%‐0), usually on the order of seconds (ms). Filter: a device used to eliminate noise, the input or output filtered to obtain a pure contention of the alternating current. Shielding: The use of physical principles, used to isolate the electromagnetic r...

  • Five things that shorten the life of your UPS battery

    Five things that shorten the life of your UPS battery

    Jun , 26 2024
    One of the more common questions we get asked is how long a UPS battery will last. The ballpark, general answer is 3 to 5 years; however that answer is generallyl. And that’s because the life of your battery depends on a whole host of factors. Those factors are what we’re going to discuss today. Here are some of the things that can shorten the lifespan of your UPS battery. Let’s jump right in. Amb...

  • What are the characteristics of industrial UPS power supplies

    What are the characteristics of industrial UPS power supplies

    Jun , 14 2024
    Industrial UPS power supply needs to focus on the design of the ability to operate in high-temperature environments. Component design must be adapted to the operating requirements of industrial environments, high temperature and high humidity, but also to cope with corrosive gases on the corrosion of the system. Operating continuously at full load under a variety of operating conditions, industria...
