STATIC BATTERY CHARGER
EBC 2405M is designed and opti-mized for charging all types of Lead Acid batteries (including jell type sealed Lead Acid batteries), protecting the battery and extend-ing its useful life time
EBC 2405M can deliver continuous charging current of 5A into 24V battery system (voltage is set to 27.6Vdc, with an option of up to 29.4Vdc) These battery chargers are designed with performance in mind and special care is taken for protecting and extending the life-time of the battery.
 
EBC 2405M is designed with “Switched Mode” technology, where the switching transistor has only two states, ON or OFF, which increases the overall efficiency, hence reduces the excess heat dissipation and in return, increasing the device life-time and reliability.
 
The control system is also designed in such a way that; battery is charged in three stages:
 
Constant current mode (protecting battery cells)
 
Constant voltage mode (reducing the charge current)
 
Float charge (compensation of internal self-discharge)
 
Constant current mode makes sure that; when the battery is drained down below its rated capacity, the high charge current flow into the battery is limited in order to protect the cells and reduce damage to the plates.
 
As the battery capacity is recovered, each cell voltage reaches up to 2.30Vdc to 2.45Vdc level, which means that the required charging current starts to reduce.
 
When the required battery terminal voltage is fully reached, the charger keeps supplying just enough current in order to compensate for the internal self-discharge (float charge). This ensures that the battery can maintain its high charge state and deliver its rated out-put current, when ever required.
