Charging parameters
Parameter
End-of-charge voltage
Charge current
● End-of-charge voltage
The end-of-charge voltage is the maximum voltage up to which the battery is charged.
● Charge current
The battery is not charged with more than the selected charge current. The
manufacturer's details for the permitted charge current of the battery must be observed.
Note
When UPS1100 battery modules are used, both parameters are automatically set, and do
not have to be defined.
The following, device-dependent maximum values apply:
– SITOP UPS1600 10 A: Maximum permissible charge current 3,000 mA
– SITOP UPS1600 20 A: Maximum permissible charge current 4,000 mA
– SITOP UPS1600 40 A: Maximum permissible charge current 5,000 mA
Reset parameters
Parameter
Reset time
Here, you define the interrupt duration for the "Interrupt output voltage" function (reset after
buffering)
Buffering parameters (2)
Parameter
Expected buffer current
Load current, which is expected at the device output during buffer operation. Please adjust
the correct application load current required. For current settings between 0 A and rated
current, the display in the diagram "Remaining buffer time" is adapted.
