Battery Charger 50Hz
Three-Phase COMPACT 3000

The battery chargers of the Compact 3000 series are designed to recharge medium – large capacity traction and start leadacid batteries.

These battery chargers are the result of the fourty-year experience in the field of battery chargers, in the application of microprocessor control systems which constanly monitorize the basic parameters that assure a correct operation and therefore safeguard the battery’s life.

“Wa” characteristic
(din 41774)

The charging curve of this model is the Wa (decreasing current charge) is compliant with DIN 41774.

The Wa charging curve, is features by a downward trend of the charging current when the battery voltage increases, therefore it takes constant power.

To obtain a suitable charge of the battery, the charger must be able to provide a charging curve as faithful as possible to the theoretical charging curve, which provides an initial charging current equal to 16% of the battery capacity, and a declining trend. With this kind of charger with standard curve Wa (DIN 41774), it is necessary to determine the charging current required, by calculating the 16% in ampere hours (Ah) of the capacity of the battery (for example: for a 600Ah battery, using a charger with 100A).
