GENERAL INFORMATION

The CB520 switch-mode battery charger has been expressly designed for the caravanning and
boating sector and can automatically charge 12V
according to the position set using the selector positioned inside.
The battery charger is protected against overtemperature and the 12V
against short circuit and polarity inversion.
The high frequency switching technology allows high performances with small dimensions and limited
weight.
6 phase automatic charging system
Phase 1: Desulphation
charged at 15.2V
Phase 2: 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.
Phase 3: Absorption
charging line, with a progressive
Phase 4: Float – Maintenance charging at constant voltage for a maximum time of 15 hours. A high
load leads to phase
Phase 5: Stand-by – The battery charger stops supplying power. It will switch over to the
phase only when the battery voltage goes under 13V
Phase 6: Refresh – The battery is charged at the
is designed to compensate for the battery self-discharge. Once completed, the charging
starts again from the
The position of the selector must be set according to the
the type of battery installed.
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.
– when switching on the battery charger, only if needed, the battery is
until the current exceeds 2A or for a maximum of 2 hours.
