EA660 Modular UPS
User manual & Operation explain
56
UPS system can be automatically converted floading charing in accordance with the battery
state.When battery is floating charging,the charging current automatically set higher than both the
current value of the converstion floating. Battery charging status converter floating charging to
constant charging. When battery is constant charging,, the charing current lower than the threshold
value of automatical converstion. And keeps 3 hours. The charging status converter constant
charging to floating charging. Automatical convertion constant and floating charging can give full
play to the floating and contant charging’
s advantages. to complete fast charging and expand battery
life

Battery constant charging process.
Battery constant charging process is constant current charging and then constant
voltagecharging.
First of all, constant current charging process. At that stage, the charging current has been set
close to the limiting value, the battery voltage was gradually increased over time. Followed b the
constant voltage process, in the stage, the charging voltage limiting is fast approaching charging
voltage, charging current is gradually reduced, at that stage that the battery is close to saturation
state, its battery charging voltage is as follows:

Battery constant charging time
The Battery constant charging time is less than 3 hours. It also is more than 24 hours.
