CB12245AJ - Battery charger with built-in intelligence

The CB12245AJ is a battery charging and testing unit with CANbus J1939 protocol.

Adel's battery care philosophy is standard in all their battery chargers to optimise the battery life. All battery chargers are housed in aluminium enclosures for DIN rail mounting. THE CB range has an automatic battery charging routine. Once the batteries have been charged, the CB series runs through a list of end of charge tests and continues to operate a periodic supervisory tests to ensure the battery is in the best charging state when required to take the load.

The CB12245AJ is designed using the latest generation of microcontrollers and over 50 parameters regarding status of the battery can be read via the CANbus J1939 protocol.

Adel System battery chargers have four charging stages and provide an accurate battery diagnosis.
