Battery Charger RE
User's Manual
3. Description
Energic plus RE battery chargers have been designed to charge Pb batteries.
These units convert the AC input voltage to a DC voltage at the correct level, in order to charge the
battery cells.
These battery chargers are fully automatic, and they are controlled by a microprocessor based
electronic board.
The entire charge sequence is monitored by the microprocessor, that is programmed to manage all
the possible operating conditions:
• Automatic start on battery connection, with 5 seconds delay to avoid sparks between the
connectors;
• Automatic shutdown on battery disconnection;
• Adaptive algorithm for charge time calculation;
• Wrong battery detection;
• Automatic weekly equalization charge;
• Two emergency timers for battery protection.
STANDARD CHARGERS [Wa]
The charge current follows the Wa curve, as
defined by the Standard DIN 41774.
After some hours, depending by the conditions
of the battery, when the battery’s voltage
reaches the “gassing” value (2,4 Volt per cell),
the LED “FINAL CHARGE” starts to flash and
the charge continues.
FAST CHARGERS [WoWa]
The charge current follows the WoWa curve, as
described by the Standard DIN 41773.
The reduction of the charge time is achieved by
applying a higher current during the first period
of charge. When the "gassing" voltage is
reached, the current value is reduced to avoid
overheats in the battery, and the charge
continues in the same way of standard Wa
models.
