Battery Charger 50Hz Three-Phase
REVOLUTION BASIC
The battery chargers of the Revolution series are designed to recharge medium – large capacity traction and start lead-acid 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.
- Charge at decreasing current with intervention of the final charge at 2.40 V/cell.
- Final charge with timed control 9h / 11h.
- Fixed charging time (equalization charge excluded).
- Equalization charge (week-end charge) to be recalled. It will start after 55’ from charge end.
- Duration of equalized charging phase: each hour 5’ (repeated for 48 hours).
- Calculation to determine the size of suitable battery charge: 16A for every 100 Ah of the battery (e.g. 500 Ah battery: 16Ax5 = 80A).
Technical Characteristics
“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).
