    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...

    Advantages of lead-acid colloidal batteries

    Mar , 28 2025
    1. Long service life: The colloidal electrolyte can form a solid protective layer on the plate, reduce the bending and short circuit of the plate when used under heavy load, delay the softening and shedding of the plate, and make the battery life reach 1.5-2 times that of ordinary lead-acid batteries. 2. High safety: The electrolyte is solid, sealed, and never leaks. There is no acid mist gas prec...

    Why battery calibration?

    Apr , 03 2025
    Definition of Battery Calibration Battery calibration refers to the process of resetting and synchronizing the battery's power management system with the device's software to accurately gauge the battery's charge level and capacity. This procedure involves fully charging the battery, allowing it to drain completely, and then recharging it to recalibrate the device's battery indicator to provide ac...

    How electrolytic capacitor work for industrial battery charger

    May , 16 2025
    I. What is electrolytic capacitor: 1. Electrolytic capacitor, as the “energy storage heart” of charger power module, bears the key tasks of filtering, voltage stabilization and transient response. Its large-capacity characteristics (up to tens of thousands of μF) can effectively absorb the pulsating current after rectification, reduce output ripple, and ensure that the charging process is stable a...
