Battery occupies a very important position in the UPS and EPS power supply equipment, how to properly maintain the battery, so prolong life, to maximize the effect? Here I will describe briefly.General UPS / EPS power supply 12V battery capacity, mostly in a, float voltage between 13.5V to 13.8V, the float voltage is too low, the battery can not be charged, the float voltage is too high, it will cause over-voltage charging, when the float when the charging voltage exceeds 14V overvoltage considered that charge, over-voltage charging can cause electrolyte in the water is separated into hydrogen...

EPS in the charger constant current constant voltage charging method commonly used two-stage charging mode or constant voltage limiting. Charger is good or bad influence on the larger battery life, you should ensure that the maximum charging current does not exceed the permissible value is equipped with a battery float voltage batteries comply with the recommended values, such as temperature compensation is better with high frequency ripple current should be controlled at a lower level. Of course, you can use other charging methods, such as cyclic charging, auto BC - float control, but the con...

EPS and UPS both have mains bypass and inverter circuit, its function difference is: EPS only functions with continuous power supply, the inverter switching time is generally less demanding (application for special occasions with certain requirements), how can output and the output of the brightest and surveillance detection function with a single battery, the daily focus on bypass, when mains power supply into the inverter, high power utilization. The UPS (on-line) is just the way the total output, generally emphasize its three functions: (A) frequency stabilization (B) for the switching time...
