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: 1000Ah – max. recharging current 200A.
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 Manufacturer.
