2.3.1 VOLTAGE DROP COMPENSATION
The battery voltage is monitored by means of the Sensing Wires. These wires carry only a small
sensing current and as such are not affected by the voltage drop experienced by the high current
carrying battery connection wires.
This provides for an accurate reading of the battery voltage and enables the battery charger to
increase output voltage to maintain the correct charging voltage “at the battery terminals” (Maximum
output 29.5 V).
Example:
Float Voltage configuration of the battery charger = 27.4 V
Charger output = 27.4 V
Battery voltage measured by Sensing Wires = 25 V
The battery charger increases the output voltage until the Sensing Wires measure 27.4 V. The
voltage drop in the charging cables is eliminated.

2.3.2 BATTERY TEMPERATURE COMPENSATION
NOTE: For further details of PC Configuration, refer to DSE Publication: 057-159
DSE94xx Battery Charger Series Configuration Suite PC Software Manual.
When suitably configured, the external PT1000 temperature sensor is used to monitor battery
temperature. As battery temperature increases, the output voltage is lowered as configured to suit the
battery requirements.
For example, the following Temperature to Voltage compensation curves are used for the pre-set
battery types. For custom battery types, the temperature compensation curve is user configurable.
NOTE: In the below chart, VRLA (Gel), Lead Acid Antimony and Wet Vented are
superimposed on each other for most of the curve.
Calcium and VRLA (AGM) are superimposed on each other for most of the curve.
Example:
A Lead Acid battery at 40 ºC is charged at 2.18 V per cell.
The same Lead Acid battery at 0 ºC is charged at 2.30 V per cell.

2.3.3 AMBIENT TEMPERATURE DEPENDENT CURRENT DERATING
The battery charger is rated at full current to 55 ºC. As the temperature increases above 55 ºC, the
maximum output current derates to keep the charger within operational parameters and to prevent
overheating of the device. An internal temperature sensor is used to determine ambient temperature.
2.3.3.1 TEMPERATURE DERATING (AC VOLTAGE BETWEEN 110 V AND 305 V)
Example:
For AC voltage of between 110 V and 305 V, if the ambient termperature is 73 ºC, the charger is
limited to 40% of it’s configured current rating.
2.3.3.2 TEMPERATURE DERATING (AC VOLTAGE BELOW 110 V AND AMBIENT TEMP BELOW 50 ºC)
Example:
For AC voltage 108 V, if the ambient termperature is below 50 ºC, the charger is limited to 25 A
maximum.

2.3.4 INPUT POWER TO OUTPUT POWER EFFICIENCY
Efficiency of the battery charger is important in terms of minimising power losses in the battery
charger and also in terms of the heat generated by the battery charger.
The following charts show the high efficiency of the DSE947 & DSE9484
2.3.4.1 INPUT POWER TO OUTPUT POWER EFFICIENCY DSE9474
2.3.4.2 INPUT POWER TO OUTPUT POWER EFFICIENCY DSE9484
Example:
With an input voltage of 240 V AC, more than 93.5 % of the input power to the battery charger is
passed to the battery. resulting in less than 6.5 % of the power being used to supply the battery
charger.
