    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, ...

    Effect of electrolyte density and discharge on lead-acid batteries

    Nov , 29 2024
    (1) Electrolyte density under different geographical and climatic strips. Whether the electrolyte density is high or low, it is necessary to make a specific analysis for the specific situation. Winter temperature is low, the viscosity of the electrolyte is large, it is not easy to penetrate the inside of the plate, the end voltage and capacity of the battery will decline, especially in the strong ...

  • Difference between kVA and kw

    Difference between kVA and kw

    Mar , 15 2025
    kVA is the unit of apparent power and kw is the unit of active power. In alternating current, apparent power does not indicate the actual power consumed in the circuit, but rather the maximum power that can be supplied or the maximum active power consumed in an alternating current circuit. In the case of active power, it is the power needed to enable the equipment to work properly, such as the ele...

    What Is UPS Input Power Factor and Why It Matters

    Apr , 12 2025
    Power factor (pf) is the difference between the actual energy consumed in an AC circuit and the apparent power. It will be calculated as a decimal or percentage between 0-1 pf and 0-100%, i.e. 0.9 pF=90%. Meaning of UPS power factor UPS input power factor UPS input power factor is the ratio of UPS input active power to input power. UPS is not only a part of the power supply, but also the load of t...
