“CB500-3” SWITCHING BATTERY CHARGERS

CB516-3 and CB520-3 battery chargers can charge automatically lead acid, lead-gel and AGM batteries with innovative charging lines. They are protected against overheating and the 12V outputs are protected against short circuits and polarity inversion.
CB516-3 and CB520-3 are furthermore designed to replace the CB516 and CB520 models.
The high frequency switching technology gives excellent performance with limited weight and dimensions.

Charging process for 12V batteries:
- Desulphation : when switching on the battery charger, only if needed, the battery is charged at 15,2V until the current exceeds 2A or for a maximum of 2 hours.
- Bulk : battery charging with maximum current until the end-of-charge voltage is reached.
- Note: the end-of-charge voltage is reached only if the battery is efficient.
- Absorption : battery charging at constant end-of-charge voltage for the time defined by the charging line, with a progressive current reduction until the charging is completed.
- Float : Maintenance charging at constant voltage for a maximum time of 15 hours. A high load leads to phase Bulk starting again.
- Stand-by : The battery charger stops supplying power. It will switch over to the Refresh phase when the battery voltage goes under 13V.
- Refresh : The battery is charged at the Bulk voltage for a maximum time of 1h; this phase is designed to compensate for the battery self-discharge. Once completed, the charging starts again from the Float phase.
