5.2.1 Thermal compensation of battery charge
This option provides a temperature sensor to be installed near the battery room in
order to detect the operating temperature. This transducer is able to interface with the
control logic of the rectifier in order to modify its floating voltage based on temperature,
according to the typical curve supplied by the battery manufacturer. It is normally used
for sealed batteries, which are particularly temperature sensitive.
The temperature measured by the probe can be visualized on the front display. If it is
outside the limits set with the software, the UPS will activate an alarm.
Picture 30 – Charging voltage / temperature curve
The temperature sensor installed is provided with a connection cable that must be
connected to an interface card installed in the UPS’ terminal board section. The
temperature sensor can be installed at a maximum distance of 15 meters from the UPS.
