ENKO BATTERY CHARGER

EBC 1205 – EBC 1210 – EBC 2405

Charging batteries in three controlled stages for best performance

ENKO EBC Series Battery Chargers can deliver continuous charging current of 5A and 10A into 12V battery system with EBC 1205M and EBC 1210M (voltage is set to 13.8Vdc, with an option of up to 14.7Vdc), and 5A into 24V battery system with EBC2405M (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.

ENKO EBC Series Battery Chargers are 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.

Benefits

Wide input range allows seamless operation under unstable supply conditions
SMPS technology increases the overall efficiency, hence reduces the excess heat dissipation in return, increasing the device life-time and reliability
The capability to continuously work into short-circuit means that a completely depleted battery can be fully charged
Elimination of fans and moving parts maximize the reliability
Low output voltage ripple allows the charger to be used as a Power Supply if required (Must be stated while ordering)
Three stage charging extends the battery life and ensures the battery is ready whenever needed
The input noise filter minimizes the EMC emitted to other components around
User operated Boost Charge function to replenish the battery charge storage capacity to high levels
The alarm output can be connected to a Gen-Set controller for monitoring.
