The CB520 switch-mode battery charger has been expressly designed for the caravanning and
boating sector and can automatically charge 12V lead batteries, with different charging values
according to the position set using the selector positioned inside.
The battery charger is protected against overtemperature and the 12V outputs are protected
against short circuit and polarity inversion.
The high frequency switching technology allows high performances with small dimensions and limited
weight.
Phase 1: – 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.
Phase 2: - battery charging with maximum current until the end-of-charge voltage is reached.
: the end-of-charge voltage is reached only if the battery is efficient.
Phase 3: – battery charging at costant end-of-charge voltage for the time defined by the
charging line, with a progressive reduction
Phase 4: – Maintenance charging at constant voltage for a maximum time of 15 hours. A high
load leads to phase starting again.
Phase 5: – The battery charger stops supplying power. It will switch over to the
phase when the battery voltage goes under 13V .
Phase 6: – The battery is charged at the 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 phase.
In most cases, the selector can be set on position “A” for led-acid batteries, on position “B” for lead-
gel batteries and on position “C” for AGM batteries.
Nevertheless, it is recommended to consult the data sheet of the battery installed.
