EBC series

• Charge lead-acid batteries in three controlled stages for optimum performance
• SMPS technology for maximum efficiency and reliability with minimal heat dissipation.

Product Description :

• The EBC 2410M is designed with Switch Mode technology.
• Charge lead-acid batteries in three controlled stages for optimum performance
• SMPS technology for maximum efficiency and reliability with minimal heat dissipation.
• The EBC 2410M can provide a continuous charging current of 10A in a 24V battery system (voltage is set to 27.6VDC, with an option up to 29.4VDC)
• These battery chargers are designed with performance in mind with special care in protecting and extending the life-time of your battery.

The EBC 2410M is designed with “switch mode” technology, in which a switch transistor has only two states, ON or OFF, which increases overall efficiency, thus reducing excess heat dissipation and, in turn, increases device life and reliability.

The control system is also designed in such a way that: The battery is charged in three stages:

• Constant current mode (battery cells protection)
• Constant voltage mode (reduce charging current)
• Float charge (internal self-discharge compensation)

The constant current mode makes sure of this; When a battery is discharged below its rated capacity, the flow of high charging current into the battery is limited in order to protect the cells and reduce damage to the plates.

As battery capacity is restored, the voltage of each cell drops from 2.30Vdc to 2.45Vdc, which means the required charging current begins to decrease.

When the required battery terminal voltage has been fully reached, the charger continues to supply only enough current to compensate for the internal self-discharge (float charge).

This ensures that the battery can maintain its high state of charge and deliver rated output current, when required.

The charger is also designed to operate with a constant power output, whereby the full output power can be delivered into the load up to an ambient temperature of 60°C.

The output power rating is linearly reduced to zero at 70°C.

This function ensures that the charger can deliver the maximum amount of power available to the load under any operating conditions without reducing the reliability of the charger.

The cell is part of the battery and 24 volt batteries contain 12 cells.

The factory setting allows the charger to charge each cell up to 2.30 VDC, which corresponds to a terminal voltage of 27.60 VDC.

The user can optionally use up to 2.45Vdc per cell, which corresponds to a battery terminal voltage of 29.40Vdc.

EBC 2405M

↑ Product description

Charge lead-acid batteries in three controlled stages for optimum performance

SMPS technology for maximum efficiency and reliability with minimal heat dissipation.

The EBC 2405M can provide a continuous charging current of 5A in a 24V battery system (voltage set to 27.6VDC, with an option up to 29.4VDC)

These battery chargers are designed with performance in mind with special care in protecting and extending the life-time of your battery.

The EBC 2405M is designed with “switch mode” technology, in which the switch transistor has only two states, ON or OFF, which increases overall efficiency, thus reducing excess heat dissipation and, in turn, increases device life and reliability.

The table shows the charging characteristics of a typical charger cell.

The cell is part of the battery and 24 volt batteries contain 12 cells.

The factory setting allows the charger to charge each cell to 2.30 VDC, which corresponds to a terminal voltage of 27.6 VDC.

The user can optionally use up to 2.45Vdc per cell, which corresponds to a battery terminal voltage of 29.4Vdc.

Each charging stage can be seen on the table.

Initial charging of the cells is achieved using the constant current mode, which limits the current so that it does not damage the cell plates.

This requires a typical charging current rating of 10% of the battery’s rated current capacity.

After the initial charging stage is complete, the charging current begins to decrease as the cell voltage approaches 2.30 Vdc.

This takes approximately 60% of the charge period and is necessary to balance the voltage of each cell within the battery.

During this period, the charger ensures a constant constant voltage across the battery terminals.

The ground connection must be done securely as the enclosure is made of metal.

Proper noise filtering can also only be activated with a good ground connection to the charger unit.
