  • Difference between transformer insulation class and insulation strength

    Difference between transformer insulation class and insulation strength

    Mar , 29 2025
    Insulation level refers to the motor (or transformer) winding insulation material used in the heat resistance level. Motor and transformer insulation materials commonly used in the grade for A, E, B, F, H five. Each insulation level of insulation materials have corresponding limit allowable working temperature (motor or transformer winding the hottest point of temperature). Motor or transformer op...

  • Why battery calibration?

    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...

    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...

  • How to maintain the consistency of lithium batteries

    How to maintain the consistency of lithium batteries

    Apr , 19 2025
    1. Balance control of the Battery Management System (BMS) Passive equalization: Through resistor discharge, the energy of high-charge cells is dissipated in the form of heat, making the voltages of each cell tend to be consistent. It is suitable for cost-sensitive scenarios, but the efficiency is relatively low. Active balancing: It transfers the energy of high-charge cells to low-charge cells thr...
