Role and application of multilayer graphene in lead-acid batteries

Jan , 26 2024

Early capacity loss of lead-acid batteries (PCL-3) - irreversible sulfation of the negative electrode The research shows that: At different discharge rates, the distribution of PbSO4 generated by the negative electrode is different. At low discharge rates (< 0.5C20), PbSO4 crystals are uniformly distributed inside the plate, and the crystal particles are relatively coarse, while at high dischar...

Switching power supply testing method replacing with visual images

Jan , 26 2024

In the daily work of FAE, we often receive feedback from users that although the system is already running normally, the results obtained when testing the quantified waveform data are not satisfactory. Why is there such a discrepancy? The problem may lie in the use of testing methods and equipment! Before conducting a comprehensive investigation into whether it is a system product issue (with a hu...

Series and parallel connection of capacitors

Feb , 23 2024

Capacitor series connection: The total capacity decreases, but the withstand voltage value increases. The withstand voltage value is the sum of the withstand voltage values of two capacitors. Capacitor parallel connection: The total capacity increases, and the voltage withstand value is taken as the voltage withstand value of the smallest capacitor. If two capacitors are exactly the same, the volt...

Choose the Smart UPS between Online UPS vs Line Interactive UPS

Mar , 14 2024

Online UPS vs Line Interactive UPS While both UPS provide full protection from major power problems, such as surges, spikes, sags, blackouts and brownouts, they differ in a few significant areas. Simply put, an on-line UPS offers a higher level of protection than a line interactive at a higher cost. More specific areas where the two types differ include sine wave output, voltage regulation, and do...
