Thermal Considerations
The thermal conditions are influenced by input voltage, output
current, airflow, and temperature of surrounding components.
TA max is therefore, contrary to TC max, an indicative value only.
Caution: The installer must ensure that under all operating
conditions TC remains within the limits stated in the table
Temperature specifications.
Note: Sufficient forced cooling allows TA to be higher than TA max
provided that TC 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
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+
output lines of each converter in order to create a droop of approx.
0.6 V @ Io nom for 24 V outputs (1.2 V @ Io nom for 48V outputs), but
this creates considerable power losses.
