Powerful and Portable Battery Charger
Description
Following a power outage, various power
engineering objects such as power plants should
be kept operating on batteries. It is necessary
batteries to be charged in order to compensate
its energy loss and keep their voltage within the
predefined limits. Battery charger BAC25A is a
portable battery charger used for charging
primarily Lead-Acid and Ni-Cd batteries.
BAC25A is intended to support the main charger
in order 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 voltage. The output voltages are
selectable in the range of 10 V to 300 V DC.
This device generates current up to 25 A. In
addition, it is equipped with thermal, overcurrent,
and over-voltage or under voltage protection.
Provided display enables users to read all
relevant information during a charging process
and to adjust the charging current, charging
time, etc.

Application example
Typical application is charging batteries that serve as a backup power supply in:
Power plants
Generator excitation systems
Substations
Protection and control systems
UPS battery strings
The BAC25A instrument 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
keeps 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 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.
