Battery Charger DV Power BAC25A

BAC25 device is a portable battery charger used for charging Lead Acid, Ni-Cd and Li-ion batteries. BAC25 battery charger is intended to support the main charger to charge battery much faster or to quickly recharge a battery following a discharge test. Using two charging modes it provides the possibility of maintaining and recharging the batteries either with a constant current or a constant charging voltage.
The battery charger BAC25A? is a stand-alone lightweight (10 kg / 22 lbs) portable battery charger, based on a state-of-the-art technology, using the most advanced power electronics solutions. It can be used in a range of applications such as:

• Power plants   
• Generator excitation systems   
• Substations  
• Protection and control systems   
• UPS battery strings  

In addition, battery charger BAC25A devices are equipped with thermal, overcurrent, and over-voltage or under voltage protection.

Intended Use Battery Charger BAC25A

Battery chargerDV Power BAC25A is a powerful solution with maximum charging power of up to  2.7 kW. It is applicable to any battery string such as Lead-acid, Li-Ion, Ni-Cd, with the battery voltage from 10 V up to 300 V and maximum discharge current up to 25 A.
The user can select two charging modes:

• IU (constant current + constant voltage),  
• UU (constant voltage + constant voltage with a current limit) 

How to Use Battery Charger BAC25A? 

Charging with the battery charger DV Power BAC25A allows you to charge any type of batteries such as Lead-acid, Li-Ion, Ni-Cd. Combined with Battery Load Unit,  Battery Charger BAC25A devices are powerful tool which enables performing detailed evaluation of batteries with tests such as cycling test.
The Battery Charger BAC25 devices is connected to a test battery using the current cables. The voltage sense cables may be used optionally. Next step is to set the current and the voltage alarm levels. After starting the charging process BAC25A devices keep the current or voltage level constant depending on the selected charging mode. When applying the IU charging mode, the battery is charged with a constant current. The voltage increases to a level close to the final voltage (boost voltage), the device switches to a constant voltage (float voltage) mode and the current begins to decrease. Cut off occurs when a predetermined minimum current value, which indicates a full charge, has been reached. When opting for the UU charging mode the battery will be charged under a constant voltage. If the battery current becomes larger than the defined current limit, the charger will switch into a constant current mode and continue charging with constant current that is equal to the specified current limit.
Otherwise, the charger keeps charging under the selected constant voltage, the current will decrease over time until it reaches a predetermined minimum value. At this point of time the charger will switch to a float charge stage and decrease to a selected float voltage.
