4.3 System Description
The ABCM Battery Charger assembly comprises of an Eltek controller, rectifier, and input and output
monitoring and control for interface circuits and batteries.
The batteries are charged at a constant voltage level with current limiting. The constant voltage, boost
voltage and current limit can be set to ensure optimum charging times whilst preserving battery life.
The controller consists of Master and Basic units. The Basic unit provides control and monitoring of the
internal system functionality. The Master unit provides a graphical user interface which allows access to
voltage and current measurements and system alarms and faults. Remote access to functions and
parameters is provided via a standard web browser, or using a PC application via SD card or Ethernet
connection.
The rectifier controls the DC output voltage, providing a fully regulated output. The charger includes
protection for over and under voltage, earth fault, short circuit and over temperature. Figure 2 details a
block diagram of the charger network.

4.4 System Components
The ABCM Battery Charger utilises third party components to provide control and monitoring of the
charger operation.
4.4.1 Controller Unit
The controller unit provides the user with a high resolution display for system status and parameter and
event information. Indication LEDs also provide feedback on alarms locally. The controller also provides
programmable inputs and outputs for remote monitoring system parameters.
4.4.2 Rectifier
The rectifier controls the DC output voltage, providing a fully regulated output. The charger includes
protection for over and under voltage, earth fault, short circuit and over temperature.
4.4.3 Batteries
The batteries are charged at a constant voltage level with current limiting. In Boost Mode, the charging
current does not change, but the voltage is increased in value. The constant voltage, boost voltage and
current limit can be set to ensure optimum charging times whilst preserving battery life.
