allows for connecting a battery-specific temperature sensor,
which provides temperature controlled adjust of the trickle
charge voltage. This optimizes charging as well as battery life
time. Depending upon the cell voltage and the temperature
coefficient of the battery, different sensor types are available;
see Accessories .
Note : Parallel operation is not possible, if the temperature sensor
is connected to the paralleled outputs Vo+, as the sensor
eliminates the output voltage droop.

However, it is possible to insert bleeding resistors in the Vo+

T A max is therefore, contrary to T C max , an indicative value only.
Caution: The installer must ensure that under all operating
conditions T C remains within the limits stated in the table

Note: Sufficient forced cooling allows T A to be higher than T A max
provided that T C max is not exceeded. It is recommended that
continuous operation under worst case conditions of the
following 3 parameters be avoided: Minimum input voltage,
maximum output power, and maximum temperature.
Battery Charging and Temperature Sensor
The battery charger models exhibit the option M1 and have
been designed to charge lead-acid batteries. The R-input
