“CB500-3” switching battery chargers

CB516-3, CB520-3 and CB522-3 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,CB520-3 and CB522-3 are furthermore designed to replace the CB516, CB520 and CB522 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.
