| |
| determined by Vrst and enter standby at the end of the charge cycle. |
| |
| It has the time allotted by Tto to do this or a fault will occur. |
| |
| until the battery reaches Vfloat. At this point the charger turns on and maintains Vfloat |
| until power is recycled. |
|
|
+/- 3% | Current used to charge the batteries during normal (bulk charge) operation. This current |
| is used when the battery voltage is greater than, or equal to Vlv, and less than Vcv. |
|
|
+/- 1% | Battery voltage maintained by charger during bulk charge. This voltage is maintained by |
| continuously dropping the output current, until Veoc is reached. |
|
|
+/- 5% | Current used to recover deeply discharged batteries; this current is used when the battery |
| voltage is greater than or equal to Vuvlo, and less than Vlv. |
|
|
+/- 5% | Current used to Equalize the batteries. |
|
|
+/- 1% | Charger goes into "soft" overvoltage mode, from which it recovers when battery voltage |
| drops below Vrst. |
|
|
+/- 3% | Current at which the charger transitions to EoC mode. |
|
|
+/- 1% | Used when EoC Mode is EQUALIZE or OFF; the battery voltage at which charger |
| automatically turns on and recharges the battery. Charger must be in stand by mode when |
| this voltage is detected; the charger will charge the battery until it reaches Vcv and then |
| enter stand by mode. |
|
|
+/- 1% | Battery voltage at which the charger switches from Ilv to Icc. |
|
|
+/- 1% | Battery voltage below which the charger will not turn on. |
|
|
+/- 1% | Used when EoC Mode is EQUALIZE. The voltage at which the EQUALIZE mode is |
| ended, unless the mode ends by reaching Tto. |
+/- 1% | Used when EoC Mode is FLOAT. Once the battery voltage drops to this set point, the |
| charger will turn on and stay on, maintaining this battery voltage. |
|
|
+/- 5min | If battery does not reach Vlv within this timeout period, an error is indicated. |
|
|
+/- 5min | Used when EoC Mode is EQUALIZE. Number of hours charger is kept at equalization |
| current, unless the mode is ended by reaching Vequ. |
+/- 1hr | The maximum amount of time the charger has to complete a charge cycle and enter |
| standby mode. Failure to complete charge in the allotted time will result in a fault mode. |
