BATTERY CONFIGURATION screen
Type Battery type (Lead Acid).
Lead - Acid Sealed Battery (VRLA).
Float voltage
Voltage to maintain battery charging (insert the value of single battery string).
Float voltage = Number of battery cells x battery float voltage per cell.
Typical battery float voltage per cell (ask the battery manufacturer for confirmation):
Lead - Acid (VRLA): 2.27 Vdc for cell 72 cells x 2.27 Vdc = 164 Vdc
Recharge current
Maximum battery recharge current.
Default setting value: 2.4 A (10 kVA) 4.8 A (20 kVA)
Autonomy time
The autonomy time of the battery.
UPS autonomy on battery mode at full load condition.
This value is calculated based on the battery type, capacity and number of cells.
Autonomy times for lead acid batteries (VRLA)
2 x 72 cells Autonomy at full load at PF=0.8 U floating = 164 Vdc (2.27 Vdc - cell)
Battery with expected trickle life 5 years
UPS Model
12Ah 28Ah (2 x 12Ah)
LP 33U Series / 10 kVA 9 26
LP 33U Series / 20 kVA - 9
Autonomy time for battery supplied by GE UPS manufacturer.
Stop Operation time
Residual battery autonomy time before UPS forced shutdown. Standard set 3 minutes.
Settable from 1 minute to autonomy time in minutes (see tables).
Capacity
Ah capacity of the battery.
Cells
Number of cells of the battery (insert the value of single battery string).
Lead - Acid (VRLA): 72 cells.
NOTE !
The values indicated above, must be considered as standard values.
The actual programmed values must be the ones defined from the battery manufacturer.
