Description
Power-One offers a wide range of battery charger systems
for power requirements of 50 Watt up to 8000 Watt.
need and optimum life expectancy of the battery. The type
of sensor needed is defined mainly by three parameters:
The nominal battery voltage (e.g. 24 V or 48 V), the tempe-
rature coefficient of the battery (e.g. –3.0 mV/K/cell) and the
nominal floating charge voltage per cell of the battery
at 20°C (e.g. 2.27 V/cell). The latter two are defined in the
specifications of the battery given by the respective battery
manufacturer.
For this purpose Power-One supplies temperature sensors
and adapted power supplies. The batteries (lead acid bat-
teries) are charged according to the battery temperature
and the ambient temerature. If the battery is fully charged it
is maintained at the float charge voltage which represents
the optimum point for maximum available energy in case of

Temperature Sensors for T and U units
For units without the Z selector switch a sensor according
to both criteria should be selected. In our example it would
be S24-2.27-35-02.
T and U units feature a cell voltage selector switch (feature
Z) to set the required floating charge voltage at 20°C di-
rectly at the unit. If this Z switch is used the 2.23 V/cell sen-
sor types should be selected in any case as a basis and the
selection criteria are only the temperature coefficient of the
battery and the nominal battery voltage. If for example a
24 V battery is used which has a cell voltage of 2.27 V/cell
and a temperature coefficient of –3.5 mV/K/cell, the sensor
type is S24-2.23-35-02. The setting on the Z switch of the T
or U unit should be 2.27.
For further details please consult the T or U datasheet.

Temperature Sensors for
M, H, S, K, KP, PSx, W, OK Units
With M, H, S, K, KP, PSx, W and OK units the sensor signal
acts on the R pin to adjust the output voltage relative to the
battery temperature and the ambient temperature. As these
units in contrast to the T and U units do not feature a cell
voltage selector switch (Z switch) the sensor selection crite-
ria is in every case both the cell voltage and the tempera-
ture coefficient (beside the nominal battery voltage).
If the application uses for example a 48 V battery with a cell
voltage of 2.23 V/cell and a temperature coefficient of
–3.0mV/K/cell the sensor S-KSMH48-2.23-30-2 should be
selected.

Fail Safe Operation
To prevent overcharging of the battery but still maintain a
minimum charging in case of interruption of the sensor sig-
nal cable to the power supply, Power-One has designed
units with a special nominal output voltage setting. These
units differ from the respective standard units described in
the datasheet in the nominal output voltage and output
current settings. Without the sensor connected to the R pin
the output voltage will be higher than the nominal battery
voltage to avoid a discharging of the battery but still lower
than the theoretically needed float charge voltage. As soon
as the sensor is connected to the R pin the output voltage
will be set to the correct value.

Higher power requirements can be covered by paralleling
of these units. Complete microprocessor controlled sys-
tems of un-interuptable power suplies (UPS) are realized
by our Applications Center. Please consult your local
