Battery Charging/Temperature Sensor
The LS are intended for lead acid battery charger applica-
tions. For an optimum battery charging and life expectancy
of the battery an external temperature sensor may be con-
nected to the R-input. The sensor is mounted as close as
possible to the battery pole and adjusts the output voltage
of the LS unit according to the temperature of the battery
(which is related to the load of the battery and the ambient
temperature).
Depending on the cell voltage and the temperature coeffi-
cient of the battery, different sensor types are available.
For more information please ask Power-One.

Test Sockets (Main output only )
Test sockets for measuring the output voltage U
cated at the front of the module. The positive test socket is
protected by a series resistor (see: Functional Description,
block diagrams ). The voltage measured at the test sockets
is approximately 30 mV lower than the value measured at
the output terminals.
In case of double output units externally connected in se-
ries for U
age is 12 V, 15 V or 24 V respectively.
