User Manual
TLE Series 625 - 750 - 1000 UL S2
BATTERY
Capacity
Ah capacity of the Battery.
Recharge Mode
Recharge type of the Battery
-
Normal
Valve Regulated Lead Acid Battery (VRLA), NiCd
without boost-charge and Flooded Lead Acid
Battery without boost-charge.
-
NiCd
Nickel Cadmium Battery with boost-charge.
-
Wet Lead Acid Boost
Flooded Lead Acid Battery with boost-charge
.
Float Voltage
Voltage to maintain Battery Charging.
Float voltage = Number of battery cells x battery float voltage per cell.
Typical battery float voltage per cell (ask the battery manufacturer for
confirmation):
Valve Regulated Lead Acid Battery (VRLA)
:
2.27Vdc for cell
240 cells x 2.27Vdc =
545Vdc
NiCd Battery without boost-charge
:
1.41Vdc for cell
284÷309 cells x 1.41Vdc =
401
÷
436Vdc
NiCd Battery with boost-charge
:
1.41 (1.55 boost-charge) Vdc for cell
281 cells x 1.41Vdc =
397
(436)
Vdc
Flooded Lead Acid Battery without boost-charge
:
2.23Vdc for cell
180÷195 cells x 2.23Vdc =
402
÷
435Vdc
Flooded Lead Acid Battery with boost-charge
:
2.23 (2.35 boost-charge) Vdc for cell
180÷185 cells x 2.23Vdc =
402
(423) ÷
413
(435)
Vdc
Recharge Current
Maximum Battery Recharge Current.
Max 20% of battery capacity (Ah).
Example: 600Ah – max. recharging current 120A.
Stop Operation Time
Residual Battery Autonomy time before UPS forced shut-down.
Standard set 3 minutes.
Settable from 1 minute to autonomy time in minutes.
Cells
Number of cells of the Battery, see “
Float voltage
”.
Example: 240 battery cells
-
40 blocks / 12Vdc Battery
-
80 blocks / 6Vdc Battery
-
240 blocks / 2Vdc Battery
NOTE !
The values indicated above, must be considered as standard values.
The actual programmed values must be the ones defined from the Battery
