CSB蓄電池HR1221W 12V21.0w 5AH緊急照明設(shè)備 門禁消防報警APC電池條

When charging Santek 3C20KS online UPS power supply float, please use the charging voltage of 2.275V/ single cell (set value at 20℃) for constant voltage charging or the current below 0.002CA for constant current charging. When the temperature is below 0C or above 40C, it is necessary to correct the charging voltage, with 20C as the starting point for each change of one degree, the single cell voltage change -3mv. 2. During cyclic charging, the charging voltage is 2.40-2.50V/ single cell (set value at 20 ° C) for constant voltage and voltage charging. When the temperature is below 5C or above 35℃ for charging, the starting point is 20℃, and the charging voltage is adjusted to -4mv/ single cell for each change of one degree.

The initial charging current should be controlled below 0.25CA.

The charge is set to 100-120% of the discharge, but when the ambient temperature is below 5C, it is set to 120-130%.

The lower the temperature (below 5C), the longer the charging end time, the higher the temperature (above 35C), the more likely it is to overcharge, especially in the cycle, the better to charge within 5C ~ 30C.

In order to prevent overcharging, try to install a charging timer, or automatically convert to trickle charging mode.

When charging, the battery temperature should be controlled in the range of -15C ~ +40C.
