5.4 CHARGE MODE
NOTE: For further details of PC Configuration, refer to DSE Publication:
057-159
DSE94xx Configuration Suite PC Software Manual.
NOTE: Should a 2-Stage charging profile be required, select a 3-Stage profile and
configure
Boost Voltage
and
Float Voltage
to the same value.
Using DSE Conifiguration Suite PC Software, the battery charger is configured to use either a 3-
Stage Charge or 4-Stage Charge profile as shown below. The description of each charge mode is
given in the following sections.
3-Stage Charge Profile Configuration
4-Stage Charge Profile Configuration
5.4.1
BULK CHARGE
The battery charger operates in
Constant voltage current limited
mode.
The charger output voltage is maintained at a constant level (
boost voltage)
to allow the battery to
charge while the load does not exceed the maximum rating of the charger.
If the load on the battery charger (
battery charge standing load
) exceeds the maximum
current rating of the charger, the charging current is limited to the maximum rating of the charger and
the voltage is reduced.
The voltage will rise to the rated voltage again once the load drops below the maximum rating of the
charger. This may occur naturally as the battery charges.
As the battery charges and the charge current drops below 75% of the current rating,
Absorption
mode is entered.
5.4.2
ABSORPTION
This mode is active for the duration of the
Absorption Timer
. This is adjustable using the DSE
Configuration Suite PC Software.
Absorption mode is used to complete the charging process, bringing the battery to 100% charged
status.
After the
Absorption timer
,
float charge
mode is entered.
